I’m not as horny anymore

I used to have sex frequently and get horny with no problem in my past relationships. My current boyfriend and I have been dating for almost half a year but I’ve been losing my sex drive, especially in the past few months. It scares me... I almost have to “force” myself to get horny. I love my bf and I find him hella sexy and attractive.. idk what’s going on! I feel so bad for him because I don’t want him to feel like I don’t want to have sex with him. I’ve told him how I feel multiple times and he understands, but I still feel bad.

Also, I think something that’s been contributing to how I feel is past sexual abuse (not from my bf). It’s been really affecting and triggering me, and it could be the reason why I don’t get as horny.

if anyone has experienced this or has advice, please let me know😕
