I'm in one of those family that are traditional and close too each other. I have sex talk I've messaging with my boyfriend when I was 15 and my mom figured out .now I'm 17 and a virgin , I masturbate but I just want to have sex but I feel guilty and wrong if I do , and my mom can tell when I lie or something. What should I do ??
