Why isn't he interested in sex anymore?

My hubby was into sex about 3 months ago and now its as if he don't even want to talk about it. Can you give me some advice on finding out whyy he might be this way?

If a man isn't into his wife, it's usually because:
A) He's not sexually aroused by her due to too many physical changes since the marraige occured, I.e., you have "let yourself go".
B) His wife is not making him feel manly and special and adored and appreciated because she's a nagging witch who doesn't do her job as a wife and instead demasucates her husband and makes him feel small.
C) He has a sexual dysfunction (emotional or physical) that he isn't sharing.

It's your job as a wife to get to the bottom of this. Sit down and ask him all three of those things. Don't take bs for an answer. There is an answer. You find it.
