I've wrestled and rough housed with one of my straight friends who I have a crush on. The first time I did it as a joke to feel him out but after that we wrestled just for the fun of it and we would go at it in class, etc. I've also rough housed with a few other straight friends. My god brother and I also tend to wrestle a lot, we once put a dent/hole through his bedroom wall and broke my older brother's bed.
I don't think I've ever wrestled with a queer friend.
