Is it normal it's affecting me this way?

Yes this is a post about being an older virgin but it's not about if that's normal etc etc it's how I react to that I'm not sure is normal.

I'm 22 soon and still a virgin, made out with someone and that's the extent of my interaction regarding intimacy.
It gives me an almost physical reaction of frustration and disgust at myself when I'm reminded of it, if I'm watching tv and someone my age or especially someone younger is having sex I'm feeling down for a while afterwards.
Despite this I'm beyond anxious of sex and have on several occasions removed myself from a situation that would have 100% led to sex, I'm ashamed of my face and body, I don't even like leaving the house till I'm wearing a couple of layers which is why I've actually put myself in this position.
Furthermore I'm not naive I know the first time is going to be awkward and fumbling as a post I read recently stated, as someone who's already got anxiety and is ashamed of my body it's something I'm worried about.
Also in my area especially my city by my age your meant to know what your doing and a lot of people have a lot of experience so on top of all that it'd be obvious I'm a virgin.
I think about it like 4 Times a day, partly due to removing myself from situations I don't really know anyone my age who single, I'm in a job that doesn't allow me to meet anyone, my friends aren't exactly bar guys either, I can't just walk into somewhere myself So I can't see this changing anytime soon which means the older I get the more anxious I'd be about an awkward time not knowing what I'm doing.
It's stupid but I feel it's really controlling my life, it's constantly getting me down and making me feel like shit, is such a strong reaction to it normal or am I overreacting?
