He's no longer attracted..

Please bear with me as this may be lengthy, and is truly something that I am looking for some serious advice on, and have been really wanting to talk to someone about.

My husband and I have been married just over a year, we are both 23 years old so we are still fairly young. We had a son almost a year ago, he was born at 23 weeks, and only lived for about an hour before he passed away. We were devastated, but we grew so close at the time that I thought we would never grow apart. A few months ago, however, we did just that. I had gotten to the point where I stopped fighting what I felt was a losing battle because I felt alone..after talking with a counselor we got back on track, and decided that we were ready to try and have another baby...I was sooo happy..I was just really at peace. As we all know in order to make a baby one has to have sex...I thought this would be the easiest part of the process..actually the best part, the most exciting part...but then I noticed that he's not very interested. I really could not understand why, each time he pulled away I asked him why with no response. Then the other night once again he's just not interested, even though I told him this was the most fertile time for me it just seemed to not matter. And finally the truth comes out and he tells me after me prying it out of him that he's not attracted to me..like when I say I'm hurt I mean I'm HURT. He's not the most vocal about his feelings all the time, but there was part of me that hoped he looked at me and THINKS that I'm beautiful, or feels blessed to have me, just really wants me. The thing is I don't even feel bad about myself..I'm not fat..I would post a picture but I'd like to stay anonymous..I have been bigger in my life, and I'll admit I've been smaller, however I KNOW that I'm pretty..I'm not saying that to be conceited..I haven't always felt this way, but I've found my confidence growing and I'm not ashamed of it. I guess I'm just trying to figure out where do I go from here..we've only been married for a year and he already feels this way, what about when we're 40 and my metabolism has slowed or I have grey hair? What if we do get pregnant and I put on 20 pounds? I just feel so confused..like my bubble has been burst and I just feel so sad. Sigh.
