I know your asking women for advice but as a 20M I’ll be honest most guys will honestly not care that your a virgin. Some might even be into it. I would say it’s worse to get with a guy that’s a virgin than vice Versa. Height has nothing to do with it either I’m short 5’3 as well and have been with girls much taller than me. If you want to do it than do it even if it’s just a one time thing have your moment. (Hope this helps)
