Yeah, I'm pretty sure many guys say "Never again" to find themselves continuing to suck cock. I know I couldn't stop, didn't want to stop either as I found myself doing something I never thought I would ever do in my life. I don't regret it at all either as I found out it was something most likely hidden deep inside me that finally escaped.
Luckily your regrets were on things you didn't get to try, I stead of on the things you did try? So that is a positive. Most guys have the post nut clarity regret and want to get out of there. I think it's an instinctual left over of when we were more primitive animals. Think about it, you just made a lot of noise, and expended a lot of energy? So you just announced yourself to predators, and are temporarily wiped out of energy - that equals you being lunch! And biologically, you did your part 'mating' wise by releasing your sperm. Until we became social animals and pair bonding, you were done, it was the females responsibility to be pregnant, give birth, nurse until the young could fend on their own. So of course your instincts want you to get out of there and not be vulnerable to be coming prey?! You were nervous on your first time, amped up by the novelty of it and risk you might get caught? Definitely bump into that guy and try again. See if he is able to host at his place where you can take your time, not be as rushed? Enjoy a session without regrets this time? Just force yourself not to try and leave right after you cum, so you can enjoy more fun?
Having those "Why didn't I do what I wanted to do?" regrets seem to be pretty normal and, yeah, more so after busting a nut. I've had a few guys who, after their first time, asked me why didn't they do what they wanted to do and how do they deal with the regrets over not doing whatever they wanted to do, usually, let me cum in their mouth, not letting me finish them off in my mouth, stuff like that. I've told them that having regrets over something that's now in the past doesn't make sense; you didn't do... something and now you realize that you should but that time has passed... but if/when you have a next time, that's your moment to do whatever you're regretting. Some guys have that level of regret before even touching another guy's prick, so you get big-time points for engaging with the guy and, yeah, you now know that you should have sucked him off and then time proved to not be your friend and there were other things left undone and you had to get yourself off. I'd tell you to not beat yourself up over what didn't happen and the thing to do is the next time you get to suck dick, you do the things you didn't do that first time - and keep having fun doing it.
I have posted this before but I was very surprised at how much semen there was. I swallowed as fast as I could but it kept cumming, my girlfriend was laughing and it began running down my chin. It was the suddenness of the situation. One moment I was working on his cock unaware that he was about to cum, then I was in shock, kind of a sensory overload.
My first time I chose a guy I knew who was bi curious and been told he was well rigged, we were in a bar ordering at the same time and I said to him, is it true about you he looked me in the eyes and said find out for yourself friend, I placed my hinde on his shorts as he became semi hard, then he simply said suck it and see how much cum you can take, his cock was about 9” and thick uncut and belle X was huge but I managed to get it in my mouth, I was surprised how fast he came just a few licks and shot a sweet huge load into my mouth, loved every moment of it before swallowing.
I'll have to comment on this from a different perspective because the only cock that I've ever sucked was my own. When I was much younger, thinner and much more flexible I could actually get half my cock into my mouth. That being said, sucking my own cock was one of the most pleasurable experiences that I've had. Feeling my lips on my cock was wonderful. Feeling my cock twitch and jerk between my lips when I reached orgasm was amazing. Feeling my cum shoot into my mouth was shocking, thrilling and intoxicating!!! Once I felt the first squirts of that salty, warm, slimy fluid hit my tongue I was hooked. Surprisingly, it wasn't gross or disgusting. I hungrily gulped it down and milked every tasty drop from my cock. Nobody knows how to suck your cock better than you do!!!
Ah true that, I don't regret the things I did do that day. Looking for ways to repeat the experience and get more out of it. Also for the other guy as I was pretty focused on me except for playing with, and sucking his cock for a while.
A lot has to do with the refractory period after orgasm. If I’m at an abs video booth and all amped up with a hard dick in hand , I would love for someone to come into my booth and give me a hj or bj. Hell, if horny enough, his dick might be in my mouth. But 2 seconds after I cum from stroking, I think “ what was thinking “ it’s like ficking my wife. I plan to clean her pussy with my tongue of any cum… but 2 seconds after i cum, I think “Naw”
It's called Post Orgasm Dysphoria. It's when all the chemicals which build up during sexual arousal are dumped into the body causing an extreme rush of pleasure and euphoria before the ultimate crash and withdrawal. It's basically a mild form of depression and melancholy.
