Kicked in the balls
Ever since I can remember, getting kicked in the balls or seeing someone get sacked has been a HUGE turn-on. However, it's only this way when a girl kicks a guy. I always feel kinda awkward talking about it with others, so I guess it's probably not normal. I often watch videos of guys getting racked by some hotties and become compelled to masturbate.
And yes, I would indeed welcome any girl to swing her foot up into my nads.
