avocet, the biological purpose that the built-up pressure we call an erection serves is to aid in spreading one’s genes by penetrating deeply and enabling a powerful ejaculation. Once you ejaculate releasing that pressure, the deed of course is done (as far as your body is concerned), and there is no need to maintain a powerful erection. Likewise, penises typically shrivel up and lose their vigor following an ejaculation. Granted, if you have an extraordinary ability to ejaculate time and time again without diminished erection quality, or if you’ve mastered ejaculation control (in which case you understand more than you let on), you don’t have anything to worry about.
The fact of the matter is that most men suffer from premature ejaculation, and women need a man to last for at least half an hour. Withholding one’s ejaculate comes with a host of benefits beyond curing the infamous premature ejaculation phenomenon. Anyway, this is quite off topic. No offense intended here. Of course anyone and everyone is encouraged to experiment with different things and decide what works best for them! Whenever I post, I can’t help but explain things from my own unique point of view.
