I don't think there's anything to be ashamed about if you're a virgin so long as you've tried but it didn't work. I knew a guy who was a virgin way into his 20's and he had multiple girlfriends, he just never did it because it didn't feel right to him. I also fondly recall boogie being a virgin into his mid 20's because he didn't meet a girl he thought was worth having sex with through shared connection if I remember. I know a lot of trans people who are virgins too, because they're simply ashamed of their bodies to the point where they refuse to do anything sexual.
I think people should remember that not all people share everyone's idea of love or sex. There's nothing wrong it so long as you at least make an effort, I think.
