I used to play regularly against this girl. She was pretty cute and I'd lay off when I had to hit her, partly because she was cute and I wanted her but also because I didn't want to hurt her.
I think she noticed because she confronted me as to why I never really hit her hard. I just kinda laughed it off. I think this upset her because the next time we played each other she spent the entire game throwing HUGE hits at me. Every time I got the puck she'd come out of nowhere and destroy me. I have no idea where this girl got her power from but she hit harder than half the guys on the other team.
Anyways, I got the message after that. She's playing hockey with the boys, she wants to be treated equally. As long as you aren't being dirty or hitting to hurt people, then it's fine IMO.
edit: And yes, we did hook up a few weeks later, was super drunk
