TMI! SEX HELP?

My fiancé and I had a pretty good sex life and we would do it often. But now I feel so bad for him because it just doesn't feel the same to me. I don't find it to be as amazing as it used to be, I don't feel pleasure anymore. It just feels uncomfortable down there ☹️ I'm still as horny as I used to be, maybe even more so now than before I got pregnant. But I can't be touched down there because it either hurts or feels suuuper uncomfortable. Is there anything I can do to save our sex life?? I hate knowing that I'm the reason he can't have sex, but I don't want him to go looking for it elsewhere because I really can't get into it. It's not fair to him or me. How can I fix this?!?!?!
