My GF said she doesn't consider it cheating if I fuck a

"Do something to give me a reason to end this relationship"

It's about the emotional side of it, more than the physical I think.
You wouldnt give two shits about some hooker

That you should fuck a hooker if you ever want variety instead of cheating on her

This.

She is immature bitch. Keep it casual and dont marry / impregnate her until bith of you are 23+ with fully developed brains.

Honestly, she probably fucking other guys too. A girl doesn't give the ok for that kind of thing unless they hold themselves up to that same rule/standards.
Y'all aren't exclusive, don't take the relationship seriously if she's not going to.
