Husband low sex drive

I am really struggling with my husband hardly ever being interested in sex. We have been married for 1 year and I have a much higher drive than him. We were both virgins when we were married and needless to say I was expecting more from him. He has RA and his doctor said meds could be causing low drive....

I ask just about every other day and only about 1 in 5 does he say yes. And he never initiates or acts excited about me like he did after our wedding.

Ive tried sending sexts, photos in lingerie, initiating at different times... only to get rejected or he doesnt acknowledge my efforts.

Everytime i try to talk to him i feel like im making it worse.. any advice in how to talk to him AND move in the right direction? I feel very insecure, angry, unloved, unwanted with him and he doesnt understand.
