As someone who posts in the Sinful thread and in the Thong thread (every once in a while), I'd have to say that the Thong thread is fair game. Where AmI, If you have read the Sinful thread, then you know that even we ladies tend to get a bit nasty in our fantasies with the Priest men. Heck, I'm 19 and my favorite band member is in his sixties! The Thong thread contains very little, if any, sexual comments ("I wanna do this to her, wanna do that", etc), so I'm fine with that. The thread would have been extinguished a long time ago had such comments existed, IMO. All I have seen are comments that show the readers' appreciation of the models in a clean, nonoffensive manner. The models that are most commonly featured in the Thong thread appear to be in their mid-to-late twenties (no prepubescent teens, in other words).
Besides, this IS 2008!! There's more sex and nudity on TV and the movies than ever (correct me if I'm wrong if 1988 was much worse), we have reality shows that are centered around models, and most of us accept and adore that ideal body figure that is most commonly seen in the Thong thread, so it won't be going away anytime soon. Its merely a sign of the times in which we live. You either like it or you don't. If you don't like it, then thats fine...thats your opinion.
Both threads have one thing in common: they cater to the fantasies of both men and women. If you don't like a thread, then simply put it in your ignore list. The pictures won't be shown (Simply an "Ignored Message" statement), so it shouldn't be a big problem.
