Why is masturbation bad?

Because you don't do the work, but receive the reward.

When you actually find and seduce women, you go through a lot, which makes you smarter, stronger, more experienced, and a better person.

When you masturbate you do nothing and receive the reward. The body gets used to it, and you become an addict. Further you go, weaker you become.

The same is true for food that gives you pleasure, but no vital nutrients...
