Well said Steve. I too have never gotten the point of sex involving pissing and/or shitting on someone else (or receiving it). Nor have I ever understood what can be erotic about degrading/demeaning someone or on the flipside, being degraded during sex.
Don't get me wrong, I can appreciate some rough and aggressive sex but I always try to be respectful to the lady regardless and I expect the same respect back.
My 2 cents only....perhaps I'm just a prude.
