How do you know if you're a good rapist? When she gets on top.
I don't really feel like it's okay to say stuff like that. Rape is a serious thing.
It's only a joke, it's not such a big deal.
This joke belittles how serious rape is and implies that women are okay with it happening. Think about how you would feel if somebody you love were raped. I suggest you stop joking about a subject that can be hurtful to so many people.
