This is tearing us apart

I need some help.

My fiancé and I have been together for 3 1/2 years. When we first started dating we couldn’t keep our hands off each other. I then started birth control and my sex drive has since disappeared.

Lately my fiancé has been pretty upset (rightfully) because we almost never have sex and he feels we’re missing a huge part of our relationship. He feels like I don’t want him or am not attracted to him. He’s craving the physical connection.

I don’t know what’s wrong with me. I’m never in the mood, and when we do have sex I have a hard time enjoying it.

I’m pretty sure it’s my birth control and other meds that I take, and we’ve talked a lot about switching up my birth control.

I want the same things he does, I WANT to want to have sex, I wish I had the drive that I used to. I just can’t seem to will it into existence no matter how hard I try.

Has anyone else dealt with something like this? What did you do? Am I just being selfish not giving him sex just because I have no drive?
