It's simply a high you can get whenever you want. If you can get it even when there's not a woman around to get it from...then what's stopping us? That's why. Imagine a woman/partner is like a restaurant...but you don't have to go to a restaurant to eat, you can eat your shitty home cooked food too. But like others said my analogy just touches the surface..in my case I usually used porn as an escape, even if I didn't do it. I was feeling down? Porn. I was feeling bored? Porn. I was feeling insecure? Porn.
