Help!!! I don't enjoy sex anymore :/

I feel so bad for my partner because he pretty much has to beg and I never initiate. I initiated tonight because I wanted to make him happy...

Everytime I have sex I have complete panic attacks and anxiety and sometimes cry. I have a long history of sexual abuse and trauma.

When we were ttc of course I initiated. But now that I'm pregnant I don't want it.

I love to masturbate though... once or twice a week when he's at work I'll use my toy.

I feel so bad because I do love him very much but I can't seem to enjoy sex :(

I also get paranoid about the baby. I know it's okay and my doctor has said so but I just can't seem to enjoy myself. What can I do? ☹🥺 it's really bothering me
