text: i know young fit men can. when i was 23 i was seeing a 17 year old senior in high school. i know this sounds retarded but he was the best sex i ever had. he could keep going and going. we would sometimes rent a room at a motel and have hours and hours of mind blowing sex. it was during these sessions that he would pull out come in my mouth and without missing a beat he would start again.  he could have been a freak of nature because since then, not one man has been able to perform like that.
