SEX HURTS 😭😭😭😭

Okay ladies. Every time I make love to my fiancee, it hurts like hell. I'm allergic to latex and most lubes. So it's difficult to find something that works. I don't know what to do. I don't ever seem to orgasm either. My sex drive has even fallen so low to where I actually DON'T want sex. Which is totally opposite of how I used to be. I hate it because I lie to my fiancee so he doesn't feel rejected about making love. And I want to pleasure him even though it hurts.

It's been hurting for 4 years now. What do you guys recommend to help this out? Keep in mind I'm only 24 and I'm in shape.
