Feeling less sexy then ever

I had a baby 6 months ago and my stomach stretched a lot I'm almost back to pre pregnancy weight but my stomach has loose skin. I don't regret a thing and I don't see the point of trying to get rid of my stomach as we're trying for number 2 and I'm proud of my belly. But last night I put the underwear he loves on and everything and he didn't say a word, didn't try to come onto me or anything. I am feeling less sexy than ever.
