This is a taboo topic - but remember our line - if taboo topics are not discussed, informed and sophisticated views cannot be made as easily.
Also, this topic can be quite...amenable to memes/jokes. While a little bit of a laugh can be ok, please have some maturity about it.
I raise this (a bit belatedly!) because of the advent of the erotica 50 Shades of Grey, read mostly by women (feel free to correct me if I am wrong). It raises a point now.
Of course it isn't 100% right to watch (and read?) it, we have our usual arguments about degradation and the like. However, to what extent should people be shunned for watching it? Should they or should they not be forgiven? Where do our expectations lie? Is the situation "if he watches it he's a bastard and should be shunned and that is that" or "it would be good if he doesn't watch it, but he can be forgiven for doing so?"
Another scope of discussion is the role of pornography/erotica in relationships. As it stands, in some relationships its central and embraced by both the male and female, in others it's banned.
Now remember, this is merely a discussion of ideas. You are not to judge other people for what they say - if people feel as though they are going to be judged for what they say, they will refrain from saying anything, and their ideas will not have any opportunity for refinement.
Also: NO TROLLING. NO PERSONAL ATTACKS.
