If it's a girl, I'd be happy and try to let her keep going. If she's super ugly or something, then my reaction would be less positive.
If it's a dude, it depends. If he's seriously a creepster and is grabbing my crotch as part of his perversion, he's getting a punch to the face, followed by punches and kicks until he's in serious pain, and probably bleeding heavily. I won't tolerate that shit.
If he's doing so partially as a joke, it depends if he's straight or gay. If he's straight, then I'd react with a "Whoa now!" and a laugh, and then a very strict warning. If it's a gay guy, he'll just get the strict warning.
That's all if I'm getting groped in the front. If someone grabs my ass, well then things are a bit different. I'd laugh and smile whether a chick or dude does it. It's a compliment. If a dude tries to do it too much, though, then it's a strict warning.
