Ok this is a little dumb,but...There is this stop and go masterbating technique thing I've heard its the stop and go. You are supposed to stop the ejaculate thats about to come out and keep doing this a lot and when you actually cu* its supposed to be alot more than normal. Well my question is when I try it I can't stop it from comin'. Right when I feel an orgasm I can't stop it. what would help me control this better and what muscles do i tighten?
