Let me first say I haven't actually read 50shades (from what I have heard it is crap) but I know lots of ladies do and I know many ladies also enjoy other erotic fiction.
AIBU to be fed up with hearing people, my BIL for example and also people on threads on the internet, compairing a lady reading erotic fiction to a man watching on line porn. My BIL 'Hahaha, she can't have a go at me for watching porn any more, not now she [his wife] is reading that 50shades book'. To me, words on a page are not comparable to internet porn, GAH!
