What to do if your boyfriend is a virgin but (Men and women help)?

My boyfriend is a great guy and we’ve been together for 7 months now. Very great guy and extremely handsome and surprisingly a virgin even though his had a few girlfriends before. He told me he is waiting until marriage and I knew from here he was a virgin even though he ended up telling me himself. For some reason I feel disgusting and worthless because I know this is the right guy I should have lost it to but ended up losing it to some druggy in a one night stand. He doesn’t know I’m not a virgin yet and thinks I am and even feels lucky to have me. He has a female friend who is also 23 like both of us and a virgin who has the same morals as him. I feel like a complete s**t and my self esteem is completely low when I’m around her. I get extremely jealous and think he should be with her instead of me but he doesn’t know I’m feeling this. What do you think will happen if I tell him since its been 7 months? I hope this is in the right section cause I’m new to this site.
