I don’t ever want to have sex (is it my relationship, or is something wrong)

I’m 22, and when I was 15-19 I wanted to have sex all the time. (I know when you’re younger you obviously have an overactive sex drive).

I’ve been in a long term relationship nearly 4 years, and honestly don’t know if we still have any feelings left besides not wanting to see each other with anyone else.

Since I was about 20 I just don’t want to have sex, I masturbate pretty frequently but when it comes to actual sex I don’t want to do it if I’m sober. It’s never as good (and I’m not under experienced or having sex with an under experienced person) I just don’t like having sex sober. I’m not as free and comfortable as I could be. Also just the thought of penis going into my vagina disgust me. Especially now that I’m pregnant I don’t even want to think about a di** going in me.

When I turned 20 I did gain about 25 pounds, but I still feel like I have never enjoyed having sex unless I was intoxicated.

Are there some people who just don’t like having sex is that normal, or is something wrong. I’m so young and I’ve been struggling with this for over 2 years (so even when I was very much I love with my boyfriend)
