Its just the way morals are today. The genie is out of the bottle. My neighbors are good people and I watched their daughter come of age. She is 20 now and sports a 'Rolling Stones Tongue' just above the crack on her behind. Pretty obvious when she wears her bikini. Go figure.
That's really become commonplace, hasn't it? I heard an anesthesiologist quoted to the effect that if a gal has a tattoo in that area, she'd better hope she never needs an epidural. Something to do with more likelihood for infection, as well as the doctor not knowing the makeup of the ink.
Makes sense, and I'm kinda surprised you don't hear this more often.
