One of the things I love to do to my wife is to balance her right at the brink of orgasm, and keep her there for a long time, just going over a little bit several times, before letting her let go over completely. She loves this and wants to do this to me, but I've tried doing it to myself by moving in and out of her pussy very slowly and trying to creep up to the brink. Unfortunately, once things start moving inside me, there's no slowing it down unless I stop. I can't get right to the brink and hold it there, and I cum. Are there any guys here who can stay at the brink for any length of time without having a climax? I need to know if this is possible, or am I wishing for too much?
