After not cumming for over a month I almost came unintentionally. I was able to retain my semen and only spill a few drops. The moment I knew orgasm was coming I applied pressure to my perineum that prevented semen from escaping. People ask me all the time about my virility and how I am able to maintain erections for hours while being on hrt. The way is not cumming. Retaining the seed will increase sexual stamina. Obviously diet and exercise go a long way to help too. It's better to control orgasm without physically applying pressure to the perineum but if you don't want to cum but you know it's coming this technique will usually work
