Virginity

Hey... I know I'm talking to a bunch of experts here so please help! I'm most likely younger than a lot of you...and yes I'm a virgin...
I'm scared af because I wanna tell my bf that I'm ready to have sex, but I'm scared cuz he's done it before... I have no idea how to tell/ask him ....I'm just really nervous and insecure about this situation.....
Any advise??😬😬😭
