21 yr-old virgin

Ok so here's my "problem". I'm a 21 yr-old virgin. Basically, I have a huge fear of getting rejected or looking too interested so I usually end up not showing the guy I'm actually interested in any attention. (I also went to a really small private high school so there were not many opportunities and all of my friends now have been my friends for 10+ years so there's no way anything's gonna happen+my college is close from home so I don't live on campus so all of the parties or clubs I go too I go with these same exact friends 😭) I didn't use to feel that self-conscious about it but I recently learned that now we are only 2 girls from my friend group that still haven't had sex and I feel like I'm missing out on something. But I also don't want to do it with some rando cause stds. So now I just don't know. Questions, tips, suggestions, similar experience? (p.s. already tried tinder not for me)
