so me and my roommates were having a debate of sorts. i find myself always fatigued despite the fact that i eat healthy, sleep well, and work out regularly. i also masturbate daily while they do not. they claim that it is the masturbation which causes me to always be tired. i find this bogus as while masturbation/sex might make one be temporarily tired for a few minutes afterwards, theres no way the fatigue prolongs throughout the day. does anyone have a scientific explanation?
