Sean: I will read more later - my roommate too. So fascinating! I don't know if I will understand ever, but it is interesting to learn.
I read link about "paraphilia". Wow. So is BIID a paraphilia for some (unusual sex interst about amputation or paralysis)? I don't mean to make this thread adult-only, but I know you won't.
Thank you!

BF here! I want to talk to him about the thread - he will say "

but may have better understanding of these ideas than me. He always says I am naeve (AD - we need a spellcheck!) - may he knows BIID before.
