Sexless marriage

I would just like peoples thoughts. If you were me what would u do? How would you react and how would u feel? I have been married for 1 1/2 yr haven't had sex in 6 months. Last year we had sex 3 times. So our wedding night I wore lingerie and was feeling excited and sexy. He told me he was tired and we will do it tomorrow and we did...then honeymoon wore lingerie again laying in bed, he came and kissed me, said ill be right back...waited 20 min, go out to the other room wondering where he is and he is watcging t.v.,
Smoking. I said what are u doing been in bed waiting for u? He says oh thought u fell asleep...um ok. Anyway we got back deciding we are trying to get pregnant so I was scheduling our sex night's and thankfully we did get pregnant right away. Through out my pregnancy barley touched me. I kept asking whats the problem and his response was there is no problem, u worry about sex too much. So I figured maybe he is weirded out about me being pregnant as some men are... Then months later I find he is watching porn every night and confronted him. It was a huge blow out, but he said he won't do it again and we moved passed it with Still no sex. Had the baby and when 2 months after I was cleared for sex we had it. That was in Aug. No sex since. we even went on a nice romantic trip just the 2 of us for 5 days and no sex. I have been turned down a few times of initing and i just wont initiate anymore. Im sure he is still watching porn but i feel so unattracrive and now even uncomfortable changing in front of him, thinking he must be disgusted of my body. He keeps assuring me that he loves me so much and he is so attracted to me but his actions dont show it and when i doubt him he gets so upset saying im overthinking it and sex is not that serious in a marriage. Am i over thinking this? Would other women begin to feel insecure? I would also love to hear a man's point of view. I just can't get answers from him and I'm feeling so down about myself lately. I feel like I have a roommate, not a husband.
