Ok, here's the deal, so listen up. One average deposit of Semen (5cc or one tablespoon) has about 3-4 million Sperm cells in it. But 98% of the slippery goodie is support and transfer factors. And most of the little guys will get carried out as you ladies drain it out. BUT!.... A few hundred thousand out of 3,000,000 will find the cervical opening and make the 1/2 inch trip up into your uterus. From there, they are chemically-welcomed and are programmed to head up-stream, into the two Fallopian tubes. At the end of each sits an Ovary. Many die along the way, and even if they make it, they may have picked the wrong tube, and even then, this month there may not be a 'just-popped-out' Ovum waiting. All this takes about 3 days before they croak from exhaustion. If a 'preggers' actually happens it's because the tube has sucked in the MissOvum and one of the remaining few little guys finds it. The now-happy Ovum moves down to the Uterus and looks for a place to implant and continue on. But 'The Pill' or IUD keeps this from happening, and the next monthly 'lady-cycle' flushes everything out. Good so far? Ovulation is usually 14 days after the onset of the previous 'Period' and then the Ovum is traveling down the tube and viable for 4-5 days. This is the basis of the 'Rhythm Method' used by traditional Catholics and others. It requires careful timing and discipline.(However, these people are also know as "Parents".) So, even with 'The Pill' or an 'IUD', to avoid preggers, with each deposit, some few thousand of the mans' sperm are gonna make it up deeper into the lady-belly, and be swimming, searching for three days. Some ladies find this highly rewarding from a female view. As in, "He had me for ten minutes, I've got him for three days." On a personal note, as I've posted elsewhere, my wife, before 'us' and married 36 yrs, had only one guy. As quite a few young ladies in the 70s did, he essentially used her as a 'semen pouch with legs' for two years, 3-4 x a week. She and I can tease about it now. But we also worked around each other then, and with her 're-fill' every few days, she had thousands of his sperm swimming around in her belly constantly and daily for two years. For what all that's worth.
Depends on his state of hydration (water intake) But it always SEEMS like more than it is 'cause it gets everywhere. Again average is 5-6cc or one teaspoon. The things we see on 'porn' vids are well-prepared by pros at that game, not the average male. As a nurse, people would say, 'but about all that blood?' and I'd tell them it's never as much as it looks like. Same with semen. If you can get a 5cc empty syringe from your Vet, and fill it with watery syrup, you'll see what I mean.
Yes, I've collected responses from various 'social-media' over the years on that 'leaking' topic. Many women find that the 'leaking' hours later in the day is quite rewarding. Examples from the file: "Just texted my husband from work and said some man must have put his sperm in me somehow cause my panties are wet." and another, "Walking across a parking lot to a store and realized my panties are wet." There are others.
Some variations I've heard and filed from (mostly older mature) ladies re: men vs women, is: "He got his, and came, and got off, but I've got his the rest of the night and still in the morning." or "It doesn't all make the wet spot. I keep some." or "I reach down and play with it later." or "I can still smell it the next day. Sexy." Yes, you ladies DO have your ways.
Sorry if this is technical, but it's factual. To be more specific: Ladies vaginal fluids are slightly 'acidic' to prevent infections (which warm, dark, moist areas are prone to). But from a sexual point of view, it's why semen is of an 'alkaline' make-up (explains the bitter or burning in the throat some ladies get), it's just to protect Mother Natures tiny seeds. Once some very few of them make the difficult trip through the 1/2" long cervix, and into the uterus, the welcoming committee shows up! And points up to the two openings into 'the tubes'. Onward! For three days the few little guys (and some are carrying girls inside) will be moving up the 2" long tubes. Some choose the wrong tube but continue on. Some meet the lady 'Miss Ovum' along the way. But with 'the Pill' that just moves down and out. Nonetheless, all the other little guys will continue wiggling around in the ladies belly. So, you ladies, and GG99, when you think it's done, he came, and it just makes the 'wet spot', or later you sit and it drips out, well, no,.....not exactly. Which, as I've posted earlier, some women find to be the best part of being a female person.
I have a file collected from various 'social media' on this topic. And most ladies report almost exactly what you wrote. The twitching and jerking, and then the "sudden wetness inside" is pretty much the standard response.
My girlfriend loves that I cum inside her and, when her doctor tells her that she can use pill for birth control, she prefers we do it without condoms just because she want to feel everything. She says she feels my excitement growing and the tension of my whole body when I am approaching the moment of orgasm. She distinctly notices that my penis becomes swollen and stretched to the maximum and that I push harder without holding back as I usually do out of concern not to hurt her. When she feels the contractions of my trobbing dick she tells it's like a trigger for her orgasm but she prefer when I cum inside without a barrier because the physical sensations are different, she can feel it's spread warm inside her. I don't know if it's mainly a psychological thing but she finds exciting that I drop all my liquid inside her, she says it makes her feel full of me and completly satisfied in that moment and after, when it drip out along her tighs expecially when she stands up, she enjoy that feeling too. Especially in this period when I have been taking arginine supplements since the beginning of the year because I have resumed physical activity, it seems that this has affected the quantity of semen and the intensity of ejaculation. If we are in bed, we put a bath towel over the sheets so as not to dirty everything and sometimes she, when I come out of her, goes to the bathroom holding her hand underneath and then takes a shower. It is something that has both physical and psychological aspects but which, in her opinion, makes the intercourse different and more complete from her point of view. And, I must say, from mine too. I find it very erotic.
So many sentences of yours in that to comment on! Suffice to say, most all is exactly what those of us in long-term relationships experience with our wives, gfs. Even the small things like the towel to prevent 'the wet spot' becomes routine. Or moving to the middle so neither has to deal with it. "...the contractions of my throbbing...she can feel it spread warm inside her...." "...I don't know if it's mainly a psychological thing..." Yes, it's both, they do. That's what most report on several confidential, academic studies. "...makes her feel full ...and completely satisfied in that moment..." That's the 'feeling purely Female' emotional aspects that are important to them. "...when it drips out...expecially when she stands up, she enjoy that feeling too...." That's also frequently reported, especially hours later or even in the next day at work or in a store. "...It is something that has both physical and psychological aspects ...in her opinion, makes the intercourse... more complete from her point of view....' Yep, she nailed it as to what 70-80% of her sister females feel and sense, whether they can verbalize it well or not. FWIW.
My wife sometimes says "oh yeah I can feeeeeeeeeeeeelll iiiiiiiiittttttt!" I don't know if she can actually feel the cum hitting her cervix - I think just the twitching and pulsating but it's hot to imagine she can in fact feel the spurts hitting and splashing all over the walls, floor and and ceiling for want of better terms.
Yeah, it's just the twitching and swelling they feel. There just ain't enough room in that tightly-packed tube of theirs. But it's interesting that many use the words "sudden warm wetness". While both bodies are at about 98.6 or so orally or on skin thermometers, our deep internal temperatures are a couple of degrees warmer than that. So the goodie actually IS a bit warmer. Similar with oral delivery. FWIW.
Oldguynurse, seems to be a font of all knowledge with this subject. I, however remain ignorant about the workings of the female sexual organs and certainly would never stretch to giving advise or real opinions on my take of sexual interaction. I have had the pleasure of 3 marriages and many other relationships to give my experience an airing. The first wife always wanted me to cum before she did as she liked the feeling of me in doing so. I sort of resented this as it usually meant that I had to remain connected whilst she worked herself up on my ever shrinking dick. (and this was an awful feeling when I really wanted stillness and calm to recover from my high moment.) In fact if she would have kept still and not moved for 20 to 30 seconds I could grow and repeat without withdrawing! Something that always gave me a point of difference to others as I could do this for three continuous ejaculations, taking longer each time. The marriage lasted 6 years, 2 children & 2 abortions. My second wife loved me sucking on her tits whilst fucking at the same time, she liked me sucking really hard, in fact insisted on it and this restricted our capacity for different positions and after a while I resented this daily routine of sucking her tits continuously (she did have gorgeous tits see Autumn Beach Party page 14) The marriage lasted only 3 eventual years and by that time I was out-sucked if there is such a thing. No children or abortions. My third wife and ongoing relationship, (now 44 years) has remained versatile regarding sex. we have 2 children. She says she can definitely feel the sperm when I cum. What I can say is with all the women I have had sex with there is always a mess afterwards and nearly all used tissue's and darted off to the toilet with a hand covering their fanny after the event. Even using tissues the mess remained on the sheets. Clean-up remained a regular everyday occurrence, as did washing the sheets. Sex remains a messy activity and I think it always will be.
Really hope I'm not coming off as a pompous ass! I just try to pass along straight info to folks. Amazing what some people have been led to believe about our complex, yet simple, human bodies. 40 yrs as an RN (now retired), and I've also done a good bit of academic research into Human Sexuality. You mentioned the female sex organs and functioning. We males, about our own carcasses, are sometimes stupid as a brick! And with Bing and Google, we have access to lots of diagrams and drawings as to our sexual internal structure, and sites like Web MD, for info on the functioning of. It's confounding to me that today we have access to more information than in all of human history, yet people believe crap from TV commercials and 'social media'! Ok, off my soap-box for now. (Oh, as to the messy part, my wife and I got to where there was a small towel under her hips, or if in a hurry, moved to the middle of the bed, so neither one got 'the wet spot'.)
