Low sex drive husband.

I wouldn't say I have a high sex drive but I definitely don't have a low one. But every single night I get the "not tonight" saying. We rarely ever have sex anymore since we found out I have PCOS. It's like the minute I found out I have something different, was the minute my husband started seeing me different. It's not like I can never have kids. It'll just be a little harder. Anyway, does anyone else have this problem with their SO? I don't masturbate because I find it extremely disturbing and I am tired of feeling disgusting because my husband never wants to sleep with me.
