Rough housing?

So my boyfriend and I always rough house and play fight. He's never hit me when we are mad and I never think that he would even do that... but when we play fight he gets so rough and sometimes it really hurts. I have a GIANT bruise on my leg from him punching me there and then there's a giant cut from where he stabbed me with his thumb. I'm not exaggerating, my leg is swollen. I'm really rough with him too, I won't lie... I'll hit him or punch him really hard or bend his fingers back.

My friends think it's weird and abusive. We rough house everywhere and in away I get turned on. It's just our thing

But my friends are kind of making me nervous bc they said that bc we are so rough they think he will hit me or hurt me for real when we aren't play fighting since he isn't gentle when we are playing around.

What do you guys think? Is it weird to rough house like that? Do any of you get turned on play fighting?
