What’s wrong with me?

Abby

I’m 19 years old and I have no desire for sex. When I was a teenager and pre teen I was always horny, like the normal amount. Now I never get horny. And that makes me not want a boyfriend. I’m always lonely and I get jealous when I see other people in relationships, but every time I try to be in a relationship I back out because it’s never comfortable. I don’t know what to do, is this normal? Anyone have any tips?
