Needed to get off my chest.

So I’m 19 yrs old and still have never been in a serious relationship or have had sex or anything more than kissing. And it’s not because I don’t long for those things. It just has never happened for me. And it’s so embarrassing to me and I think about it a lot. I feel like it’s so weird to be 19 and still have never had a boyfriend. Is this a normal thing? Is it me?
