I say it up to the person, and what does it for them. As long as it is legal, of course, but other than that, if its what you like, go for it, no matter how disgusting or perverted. I have been told by friends that I'm really open-minded and unshockable, so.........
I also bought myself a 'Warning - Rated 'H'' T-shirt. lol. Make what you will of that.
