Telling my mom about this


How do I tell my mom I lost my virginity ? I’m only 15 . She doesn’t know I have a boyfriend I snuck him into my house and his mom fount out now she wants to come to my house talk to my mom but I want to tell my mom before this happens what do I do ? How do I tell her ?

Update :

What I was thinking about doing was sitting my mom down and telling her I have a boyfriend then sit and talk to my boyfriend and tell him if his mom can come over and we tell everything else to her is that a good idea ?
