Very intersting poll!!! I love all the possibilities. I hesitated a lot between :

- The writers wanted to suggest emasculation but have no intention of actually following through (aka they want to create an allusion but it's not what happened)

and :

- Foyet meant that he can have sex, but he actually likes stabbing more and Hotch also understood it that way via implication/conversation alone that stabbing has it's own appeal, on its own merits and Hotch will consider that during his next profiles

I voted first one...

But all the suggestions about the networks restrains are also very tempting...
