Pcos/sex

So I’ve been seeing this guy for about 3 months and everything is great, especially the sex. I have PCOS and I’m not sure if that has anything to do with it but I have like no sex drive. I want to like once a week maybe and we have it 3 days a week or so but I have no desire too. I do it to make him happy. He has never said anything when I turn him down but i know it bothers him and makes him feel like I don’t want him because i do, i find him incredibly attractive and he knows exactly what to do to turn me on. I don’t know what the point of this was but I just don’t know what to do anymore.
