My ex and I had anal sex for over 3 years she would use toys on her clit then ask me to penetrate her ass, she I assume was in the process of having an orgasm which she would hold back till I was ready to come in her ass, its a great feeling your partners vagina throbbing whilst your coming.
I don't think that anal sex orgasms really have anything to do with the vagina. On almost all women, the "G-Spot" lies on the anterior wall of their vagina, that is, if she was laying down, it would be on the top part of her vagina. Perhaps, depending on the position, you could have an orgasm via anal, but vaginal stimulation. I think this would only be possible through missionary, though. When you are doing it in "doggy style", the penis primarily contacts the posterior wall, not the anterior wall.
Although women obviously don't have a prostate gland which will create an orgasm when stimulated, I remember someone in these forums suggesting, quite plausibly in my opinion, that given the right circumstances & angle of penetration, the G-spot could be being stimulated through the anal membrane.
This makes sense - diff angles in anal allowing for indirect stimulation through the anal/vaginal wall. Speaking for myself here, ... each to their own. Anal doggy with your chest up and a slight back arch (angled towards anterior wall) feels nicer than if you drop your head and chest down (angled towards posterior wall). Dropping your chest down is a good way to relax and get used to it tho, ... kinda the path of least resistance lol Likewise, it is nicer in doggy if the guy is in a kinda cowboy stance standing over tha back of ya and coming down at an angle (anterior angle) than if he has a dead horizontal line up behind ya with no angle. In cowgirl fwd or reverse (my fav way), just the same as in vaginal you get diff sensations from slight angle adjustments, ..and in both cases, leaning back slightly (again hitting anterior wall) causes sensations that just are not there if leaning fwd (hitting posterior wall) ....and I dont even know what the fuck to call what we did this afternoon but somewhere among tangling ourselves up, we both ended up flat on our backs, head to toe, his dick in my arse, ..and he wrapped his arms around my thighs and pulled me towards him which was kinda making my pelvis not butt up against him, ..but roll up and over his then slide back down to the bed again. I can't explain it properly, just happened and I would have touble sorting it out intentionally for a repeat lol. Anyway, enough of the gore (lol) but the first time he pulled me towards him we both went, 'oh fuck' at the same time over how intense the feeling was. Definately some major anterior wall rub going on there and the orgasm was so good I had tears down my face. As for him, major knob rub, and besides his obvious pleasure at the time, he just rang me in the middle of writing this (twice) just to tell me how good it was again lol. So yeah, my (albeit limited) experience indicates it is the vaginal erogenous zones being stimulated, and the angle of the anal having everything to do with it. Only bit I dont get if this is the case, is why I go off more for anal if it is the same spots being stimulated. hmm? anyway ... To get back to a point made at the start of the thread tho (2nd post maybe?) people can orgasm from all sorts of different stimulations, even just mental kinks, ... so the presence or lack thereof of any specific peice of anatomy in a females arse is irrelevant to some degree. Only explains why it should theoretically on a purely physical level be even better for guys. We can't speculate tho on what the mental and or emotional contribution is towards orgasm for any given person in any given instance, but it is said by some that a womans biggest sex organ is her brain. Bah - who needs a prostate! ( ...besides dumb bitches with no brains j/k)
It takes very little other stimulation for me to cum from anal, but a good rub of the clit while getting it sends me thundering to orgasm, so it's difficult to leave it alone But I think because I get such good orgasms from it and anticipate the intense sensations so much before that it really ads to the arousal and can make it relatively easy to get there once he slides in..
My wife doesnt cum from anal but after anal shes ready to cum quickly thereafter. We do mostly anal nowadays. I can get her off with just a few fingers after anal. It gets her going, for sure!
Have her on her stomache and be on top of her. She feels it in her ass and pussy. At least that's what my girl said
Oh man! I would fuck my ex girlfriend in the ass on a regular basis without any other stimulation and she would cum multiple times. She would have 5 orgasms within about 20 minutes laying on her back, legs in the air on the edge of the bed with me standing. It was amazing! We rarely had vaginal sex and when we did she wouldn't cum nearly as much and not nearly as intense. For an anal freak like me, it was awesome! I guess it just depends on the girl. I've only recently been able to talk my wife into having anal sex and I try to make it as enjoyable as I can for her because she is extremely shy about it. Last time we did it I rubbed her clit during and she came right as I started cumming in her ass and she literally said "I can't believe that happened!" because she was so close minded about before.
