There are plenty more. And there are cases where both parties have been charged. I don't have access to Lexus-Nexus and I don't feel like looking them up anyway. But I presume you get the point.
Interestingly, there are references to "the female breast" in the Arizona Code. Shouldn't the "male breast" be equally sacrosanct by your standards?
I do not believe that either would be charged if both were 12 years old. That would be pretty damn silly, though I would not argue the point that some idiot had charged both. As for the breast. The female breast is considered a sexual organ, while the male breast is not. I will leave it to you to decide if this is correct or not. Though we rarely agree on anything but jokes, you are not an idiot.
