That's what porn is for men - a cuckold compromise.
You're young, you don't have a girlfriend and there's no way for you to have sex in the foreseeable future. You don't even know how sex is like, but you're curios.
So you start by looking at pictures of women and maybe try to imagine stuff with them, but you want more, you want what's normal, what's natural, to actually have sex with her.
But you can't, and realistically speaking, those women would not want to have sex with you either anyway, you're too young, too inexperienced, too different to what they like and they're used to.
So you do the inconceivable compromise and sacrifice your own manhood just so you can "get some".
You are allowed to watch - to watch her get f#cked by another man, while you masturbate next to them. In a way, you're closer to "sex" than you've ever been in your life, in the other way, you're the farthest away from sex a man can possibly be - another man is inside the woman you want, while you're stroking your dick watching, ejaculating in thin air/ on yourself.
The ultimate submission act. Take a look at yer tiny cock. Be ashamed
