Is it normal i want to do this really badly

There's this girl who's a year older than me and I dated her a few years back for a little bit but nothing happend. She is kinda crazy. Also She is very pretty. But whats strange is how athletic she is. She can do a standing backflip and all other crazy acrobatic stunts. She is really aggressive to. I'l cut to the chase there's no chance of a long relationship with us but she's so aggressive and crazy that if we were having sex she would hold me down get on my d*** and ride it until she passed out. I don't like her but I really want to have sex with her because she is that kind of crazy chick that's got to be a freak in bed and i find her incredibley attractive. Is this normal?
