Husband has lost interest in sex.

Hi-this is a long one sorry. I am a 33 husband 38 we have been together for 11 years married for 5 this month. We have had a good sex life for most of our relationship. Last year we went through a rough patch in our marriage followed by my husband going to counselling which led to him being very open with me about some sexual things (preferences etc.) that he had been hiding from me for our whole relationship. One of those things is that he looks at a lot of porn. Early in our relationship I had asked him about what he likes if he likes porn etc. me being my 22 year old sheltered self didn't look at porn and didn't find it a turn on at all. He told me he didn't like it didn't enjoy watching it etc etc. I never questioned him. Fast forward 10 years and i find out not only does he in fact like porn he likes pretty hardcore porn. He has been watching it almost daily and masturbating for our whole relationship. I am very open to try anything at least once so once he told me about some of his fetishes we have done a lot of experimenting and it was great! Things were wonderful for about 6 months we were being so honest having great sex, I felt so close to him. I found out i was pregnant (happy surprise) and we moved to a different province into a much smaller condo. Through my whole pregnancy sex was basically non existent. When I tried I often got turned down. He rarely even touched me for cuddles or anything. I gained a lot of weight during my pregnancy and my body is no where near what it was. Since baby was born 8 weeks ago we have had sex once. I mean I haven't been overly in the mood but it still bothers me that he doesn't even try. I feel he isn't attracted to me anymore. I have felt like that since becoming pregnant. We have talked about it at length and his responds is that "he" isn't happy with the way he looks and that is why he doesn't feel sexual. BUT he is still watching porn and masturbating so clearly he does still feel sexual but not towards me. I heard him masturbating in the bathroom this morning and it really upset me. I didn't say anything as I know he would just deny it and turn it around that I was being insecure or something. I don't understand why he'd rather go solo than be with me? I also feel betrayed that he lied for so long and now feel paranoid about it. I don't even care if he does watch porn and jerk off what bothers me is that it feels like he would rather do that than be with me and don't lie about it! I am at a loss for my next move. Whenever I bring it up we end up fighting-he denies it and I just don't want to fight about it anymore. I feel like shit about my body right now as it is after just giving birth so I don't want to try and get dressed up and seduce him or something. Sorry for the long post I'm just hurt and angry and at a loss at this point. I need a male perspective that isn't my husband.
