People, listen to me; i’m 18 years old, i know a thing or two about jerking off. And i’ve done it all. I’ve jerked off 10 minutes before a workout, i’ve jerked off 10 minutes after a workout, i’ve jerked off the morning of a workout (twice the other morning pre-workout actually), not at all before or after a workout, not to mention i’ve jerked off every single day this week (twice on tuesday) for the past 6 days, and i’m doing just fine. Energy is good, workouts have been good, everything’s going just fine. If anything, being aroused pre-workout open up the blood vessels and allows more sh!t to happen during the workout. Just because you lose sperm, doesn’t mean you’re losing testosterone. The old gym coach cliche of not jerking off before games is stupid. If you’re jerking off, endorphins get released and you’re happy. If you’re happy, your energy will be greater. If you’re energy’s higher, your workout will be better. It’s common sense.
