Is it normal to get turned on by a cute girl hit in the crotch?

Ever since i was little i alwasy got, if not just a little, turned on by a girl getting hit in the crotch. Im average with other things that turn me on like body contact and hot kissing, but i never understood why something like a hit-below-the-belt to a girl turned me on? its not just little too, ive asked girlfriends, and girls at school about getting hit down there, strangly enough they told me but with little detail, (mainly because they couldnt quite remember). I always have an urge to just give a girl a little wack down there. Now I dont hate women either, its not any type of hate thing, im sure of that.
I feel like im the only one here, is it just me? am i weird?
