Our sex is breaking the deal!

My fiancé is a very private person, so I don’t have a lot of people to talk to this about.

We’ve been together for three years (engaged after two months!) and he is just the most perfect being I could ask for.

When he was in college, he was misdiagnosed with an STD (one that isn’t curable) and it basically shut down his sex life. He didn’t have sex for 6 years and focused on other things. He dated one girl for about a year before he met me and she suggested that he get retested. That’s when he found out he was misdiagnosed.

I have always been a very sexual person, more active and dominant than most of my friends. He is literally the exact opposite of me, which was no problem at first, but now I can’t take it anymore. We had a big discussion (which turned into a fight) about why there is no electricity between us in the bed room and that’s when I put two and two together- that the misdiagnosis destroyed his sex drive. I am so unhappy with our sex life that I have contemplated ending our relationship just so I can have mind blowing sex with a rando. I love him so damn much and feel beyond selfish and mean for prioritizing this issue, but it’s been months since we’ve had decent sex and I am 24. We have not begun wedding plans but I’m scared to even think about planning until I feel like we are getting on the right path, however he is just so reserved that he can’t seem to verbalize how he plans to work on it other than “I’ll work on it.”

I don’t really know what to do. I can’t even imagine ending our relationship because the sex is bad, but I cannot possibly continue at this pace.
