Long story short; been married 5 years together for 10. Have a 4 year old son together. No major issues in our relationship or marriage, some would say it was perfect. Nobody’s relationship is but I’d say we felt it was close. We get on well and I can’t honestly complain about him, he has never and would never do anything to hurt me or our son, he works hard and is kind and affectionate. But, the last year or so I have not wanted to have sex with him at all. He is a good looking man, but I’m just not attracted to him, I don’t want him to touch me. We have had sex a few times this year but I don’t enjoy it, I feel awful because I feel like I’m lying to him and lying to myself, but I almost become detached when we do have sex because I really don’t want to. Like I say, he is a kind and lovely man and other than that (major) issue, he is a good husband, other than the usual little niggles everyone has. What do I do??
