As a guy, trying not to cum often feels like those mini-games where you have to keep a needle in the middle of a green zone while different factors try to push it left or right. You think you’re about to finish? Better start counting prime numbers in your head to distract yourself. Nope, got too distracted and now your erection is starting to go away. Now thrust harder to compensate and you now inexplicably feel like you’re going to orgasm while having only a semi-erect penis.
Then to top it all off, sometimes you “stop” just a millisecond too late and you get this pathetic 5 percent orgasm where you feel virtually nothing, don’t actually cum, but your dick has decided that the show is over and retreats for winter. Then you have to try to explain what just happened to some poor girl who thinks she did something to instantaneously kill your erection without any hope of it returning.
