I need some help, I just have to last longer. I actually read in a magazine one time that an exercise to help with this was that when you were masturbating and about to cum, grab and squeeze the head of your penis for like ten seconds or something. Then you are suppossed to repeat the same thing either one or two more times, and then let yourself cum. You are suppossed to do this everytime you masturbate. Has anyone ever heard this, or does it even make the least bit of sense.
