Bad sex

Ladies.. help a girl with a super high sex drive out. I’m struggling with my current sex life. My partner has a medical condition meaning his libido is really low. Whilst I try and be understanding, it’s really starting to affect me. I suffer with extremely low self esteem (I had an eating disorder a few years ago and with this I was a size 4 and 7 & a half stone). Now after two children, I’m feeling really self conscious. I don’t feel attractive to my partner, he tells me I’m beautiful but he doesn’t show me that he still finds me sexy which knocks my confidence. I’ve explained to him how the lack of sex makes me feel and even if he can’t “perform” it would make me feel better if he could meet my needs in other ways but he always chooses not to, which reconfirms that perhaps he’s no longer attracted to me. What do I do? My mental health is really struggling with this and I don’t know what to do anymore. I don’t feel good enough and feel like I’m constantly forgotten about. Don’t get me wrong, when we do have sex, it’s amazing but it’s becoming more and more rare and I don’t know what to do anymore. Feels like I’m living with my friend and not the man I’m supposed marry in July and I can’t help but feel like sex is a huge chore for him.
