When I was very young just starting out in South America I used to come the first time and be like real casual, kind of let it just slip out so the lady wouldn't realize it-then just keep on pumping without ever missing a beat and come a second time about a half hour later. I was very young at the time and the women thought I was some kind of legend being able to go for so long at that age and putting them in all sorts of porn positions to do so!
I was just trying to get a two for one.
Now I take my time and thoroughly enjoy the journey, couldn't care less how many times I come, but generally once is enough.
