Hi,
I have noticed the rules and wondered the same thing. I like to think that using slut, bitch & whore would be okay. IMHO, of course. I am a female too - and i think it would be a little hard to get guys all excited calling using the more tame terms when describing that pecker up her butt...
Coming off as a phonesex girl.. I couldn't imagine NOT being degrading to myself. lol It sells me.
To each his/her own though..its your site and i would respect your rules and even trying to be a bit..tadbit tame so i can get listings to sites who may just pick up on the trend.
