I actually convinced my girlfriend (who is now my wife) to wrestle one of her friends. This was, of course, before I revealed my fetish to her. First rule: Alcohol helps definitely helps! We were all out at a bar and her friend was staying over with us that night anyway. I think UFC was on TV and that's how we entered the discussion. They wouldn't fight so I asked if they'd ever just wrestle. They just laughed, so I jokingly said, "OK! Wrestling match tonight when we get back!". Everyone forgot about it except me of course. When we nearly arrived at our place in the taxi I reminded them about wrestling. We were all drunk and having a good time. My girlfriend's friend shouted from the front that it was on! My girlfriend was sitting next to me in the back and whispered in my ear, "she's bigger than me, what if I lose?" (she's quite petite). I told her it didn't matter and to try her best. It started with some arm wrestling with another friend who didn't want to wrestle, and then we got into the playful wrestling match. Best thing is that I got everything on video so I can relive it whenever I want to :-D. Unfortunately, before you ask, I don't think my wife would approve of me sharing it publicly.
Another bad thing that came out of it was that the friend she was wrestling rolled her ankle and it was sprained pretty bad. To this day whenever I mention her wrestling again she says she doesn't want to roll her ankle like her friend...still working on getting her over that fear!
