What can i do so my husband can desire me again?

I am 22 and my ( common law ) husband is 38. We have been living together for six months but have been together for 2 1/2 years. Before we moved in together, sex was great. Any chance we got we were on it. We would go to motels, do it outside, in the car, anywhere we could. There was always a deep connection between us that anyone could probably feel miles away. It was always so intense. We could go at it for hours and several times. I suppose it was like that because we couldn't always just do it when we wanted to so when we got the chance it was just so exciting. When we moved in sex was great for the first two weeks...then my hubby came down with a bad flu so we didn't have sex for maybe a week. After that we started having sex again but maybe every other night. Since then the sex started becoming less and less. I am a big horn ball. And he was too before moving in. now its been six months and i don't know what to do. Whenever we have sex its because I initiate it. It makes me feel undesirable that he never initiates it anymore. Sex has changed so much in the fact that he doesnt even touch me, kiss me, look into my eyes..I feel that he is only "going along with me". We have been trying to conceive and so we have to have scheduled sex. We will have sex daily for about ten days during my ovulation time. But after that, nothing if i dont initiate it. He could probably go with no sex till its time for our scheduled sex agian. I feel like he thinks of it like a job he has to do. And once we start his goal is just to finish. Not to connect with me and please me or anything else but to just get his sperm in me...Its so stressing and It hurts me so much. Another thing is that he likes to receive but not give. It frustrates me that aside from me having to initiate it all he time, he wants me to give him bj's but he wont go down on me. In our whole relationship he's done it three times. I ask him and talk to him about how much more i'd like to receive but nothing ever happens. I ask him if he still finds me attractive and he says yes. But he doesnt show it. I try to dress up for him and look sexy but its like he doesnt even notice. I'll prance around in front of him in something new that i just bought to look sexy for him and he wont notice unless i say something about it. I am overweight and have terrible self esteem and that only makes it worse. I have always been fat and before he would always want to be touching me, grabbing my butt, looking at my boobs, etc...now nothing at all. Not even a compliment. My hubby used to call to me during his lunch breaks then stopped. I found out that he would much rather see porn on his phone than call me. We talked about it and I asked him to stop. He told me he would and blah blah blah...A few weeks later I catch him still watching porn. It pissed me off and made me feel terrible. He is getting his needs met with his phone porn instead of me. It made me feel so bad that he obviously gets a thrill with that and not me. Also, brings down my self esteem cuz he get a thrill with those skinny girls. Supposedly he has stopped, but I doubt it. It depresses me that we are going through this so soon. I can just imagine years down the road. I love him with all my heart. I would want this to get better soon because i;d hate to leave him for this reason. But truth is that I need to feel desirable. I need to feel that he really wants me. My toy gives me a cheap thrill, nothing close to what he would give me. And i need to feel that again. At this point im beginning to think whats the point of even trying to have sex. My toy satisfies me for a bit but it cant kiss me, hug me, hold me, touch me, connect with me...but then again, my husband doesnt do any of that anymore either. In the beginning we talked about how important we thought sex was in a relationship and we both agreed that we thought it was very important. It doesnt seem like it anymore on my hubby;s part. I've tried talking to him but he just wont talk to me about it...or just goes along with me and agrees to everything i say but never steps up to the plate. So please, any suggestions On what I can do next? Im on the verge of giving up and just not having sex...but in the end, a sexless marriage just isnt going to work. :(
