Alright, I'll post it. If you find it inappropriate, I won't whine if you delete it...
I've always been into sports, and a few years ago, I started boxing at a local gym to get in shape. Once every week, I get in the ring to spar - very lightly - with someone else.
Tonight, I sparred with a woman and something unusual happened. The sparring session went normally - we don't hit each other hard at that gym - but something was unusual. For a reason that I don't understand, every time that she managed to land a few punches in a row, I got a little... turned on. You know, with an erection in my shorts.
And... I'm not too proud of this. I never expected to get sexually aroused when doing a sports activity, even less when boxing!
Am I discovering some strange fantasy? Should I seek some help? Does anybody have an answer, an explanation or advice to give?
