it's okay to feel hurt, yes. But deal with that hurt in such a way that it doesn't end up crippling yourself.
It is, as long as you consented to it and able to bear the responsibility and/or future consequences of your actions
no its not no one should be hurt
It's how you learn from your mistakes. Just don't let your self let it go too far, like me.
If you're a crazy person that gets turned on by pain, then yes definitely.
