when i first started datin the gf i could last probably hour or so or just go for long ass periods of time. now ive calmed down and learn to enjoy but i sure as hell dont last as long. I can say she will pretty much cum everytime. last from 5 mins-30 mins but more than that and i can say it can get boring if not in the right mood. im average but hell the gf loves it and thats all that matters. maybe he feels alot of you, if its tighter the sensation can be unberable at times
