I've always been amused by the no fap "religion" and increasing T levels.
First, it's been proven that looking at pictures of naked women can immediately increase T levels by significant amounts. The effect is surely larger than that of no fap. Ideally, you'd be spending your time with naked women in real life, but if that's not possible at the moment, then at least look at pictures of them whenever you feel like it.
Second, you need to release the fluids that build up in your system. No fap is surely not healthy in that regard.
Third, if you have high T levels, you will be horny all the time. No fap would become unbearable. I believe MPMD actually did a video on this (about trying no fap while on steroids).
