Not wanting sex 😓

So I don't really know how to deal with this?

About a month ago I went in for a pap smear that came back abnormal. I got biopsies done and I have a treatment for mild abnormal cells later this month.

But ever since I got that call, I felt off. Like, something is wrong with me, with my vagina.

I haven't really wanted sex because of it. Actually, I'd say I have been completely turned off and can't bring myself to have sex. Every time my husband asks, I get this thought of "something is wrong with you" and I just can't. He tries his best to put up with it, but I know he is wanting sex.

We have a rule in our relationship that if the other person does not want sex, porn is allowed, but he still doesn't really like watching porn, he'd rather actually have sex.

I know its entirety a mental thing, and I am going to work on it in therapy. But I was curious if anyone has any tips or anything they could share?
