Happens to me all the time, pepe. I do believe, based upon my experience, the longer you can edge, (reaching the point of orgasm, and then backing off, again and again), the bigger your gains tend to become, especially flaccid. When I do a half hour to hour edging session without ejaculating, I'm "flushed flaccid" throughout the next day. My bulge is obscene. Whooohoooooo!!!!
Do the best you can, that's all. For each P.E. session you can avoid busting a nut, the better the next one should be.
