Lost sex mojo

Hi ladies.

My husband and I have been trying for a baby for over 2 years with no luck. I have pcos and am under a fertility clinic. They told me that it's 'unsafe' for me to be pregnant due to my weight. (13st 10lbs) since the last appointment our sex life has been awful. My husband wants sex, initiates it but it's not him it's me. I feel disgusted. It feels like a chore. I don't enjoy it. I hate it when he touches my nipples. I hate the feeling. I give up on his advances and eventually go through with it just to please him. When he's thrusting there's a dull ache. I don't even orgasm through sex. Is there something wrong with me?!
