I think for motivational support (e.g: To get hoes) Practicing abstinence with masterbation/sex is a good idea. I feel alot more applicable to working out knowing that women really like guys with bodys and knowing that by doing this I enhance my chances of getting laid this saturday. Science plays its role in this aswell. darwins theory "survival of the fittest", women instinctivly want a guy that can defend her and protect her in the wild, men instinctivly know this too, so to get ready to be chose they workout as hard as possible. What happens when the male jacks off and doese'nt care about what the women think? All motivation to look good is gone.
So please guys, don't whack off too much!
