Very creeped out, what do you think?

My husband is into s, Im not. He always fantasizes about them. Then the other day he told he could see our neighbor across the way undress(we live in an a apartment complex) He told me he would try and watch her every morning. He then told me he knew which apartment she was in and look her up on a social networking site and send her a message to see if she wants to have with us!!! He's also tried to involve random coworkers!! I think hes crazy, he wants me to believe hes having a litttle fun! He has very weird es as well, that I find disturbing, humiliation and stuff, he wants to be humiltated!
