Struggling with Low Sex Drive in Engagement

My fiancé isn’t interested in sex like he used to be. We have probably

had sex twice in the last year. We didn’t even have sex on our engagement night.

He tells me he simply isn’t interested and feels bad that his sex drive is so low.

I tell him I completely understand this as I have dealt with low sex drive myself in the past.

We have been together for 7 years, it happens, but this feels different. I’ve tried to initiate,

I’ve asked him if he could tell me when he feels like he is in the mood, I have asked him

if scheduling it would work, and nothing seems to be the solution. I asked him if he

thinks it could be a medical issue and he said possibly, but he doesn’t want to go to the doctor
