Is it normal to masturbate to videos of girls kicking guys in the balls?

I'm a guy and I like masturbating to videos of girls hitting and kicking guys in the balls. It turns me on even more than normal porn. I especially like it when the guy is naked and the girl can see his boner but she keeps hurting him down there. I keep imagining myself as the guy begging her to stop and saying that I'll never be able to have sex again. Being so powerless and helpless sexually excites me.
