How can some guys c*m by ONLY getting f*cked?

I'm talking, no touching or rubbing. Zero contact with his sausage. The rare times it's happened, I always found it fascinating. I've seen some stock answer about prostate, but I want the tight, wet, and gushy answer.

physiologically speaking, erection and ejaculation are two different entities, erection is parasympathetic, ejaculation is sympathetic, basically you spark an erection, you keep the high building, till sympathetic takes over, contracting the whole pelvic wall, and squeezing the prostate to give seminal fluid and the last fourth or fifth "root" of the penis, now this has multiple elements, how it is "supposed" to work, is continuous friction and stimulation of penis leads to that threshold being crossed, which is why many bottoms even if hardcore need to be stroked, note that most of it is prostatic fluid dribble, but it is still a mental threshold, and the stimulation of the prostatic wall coupled by a certain mental state of being subject of desire and penetrated can lead to sympathetic takeover and ejaculation, the fantasy also matters a lot..

Whatever. Where are the cockhounds to chime in???

oh lol, forgot the tight gushy answer, I find going without for a couple days while edging helps, also the connection and, well feeling overwhelmed, a bit of humiliation works, doggy doesn't work for me even if it allows stronger pounding unless she is large, cowgirl/boy or missionary are better, also that bit about fascinating, my first ever tgirl LOVED that I did, she never forgot it and always tried to recreate it, even got upset at times, wanted to see me "shoot for the heavens" again lol.

I was once getting f*cked by a girl in Orlando and she made me cum without touching me. Only time it has ever happened, I’ve been trying to recreate it since ... I was on top but she was pounding hard from below ... and there was a hint of humiliation. And a perfect fit. The right recipe.

when i get f*cked by a big hard dick i cum no hands

[oooh]

That happened to me few times. All they need to do is fuck me hard and fast for over 20 or 30 minutes. Some tops were surprised when I came.
