We don't know what to do

Emma
My boyfriend is 19 and I am 16 and his mom found a condom wrapper in his room- when our pareants met they said we could not have sex, but I mean here we are, i don't want to put his mom in a bad position but I also don't want my parents to know. We are going to stop being sexually active but we don't know what to do......can I get some advice or help?
