So i have a LTR who's 16 years old. One day we were texting, she was at school and i was home.

She sent me a text in which she told me that she and her best girl friend were talking with one of their classmates about sex and that he was "learning" them. Once i teased her with sth like "you're too young to talk with you about these things"( obviously joking) and while she was telling me that her colleague teaches them about sex (in a laughing manner) she remembered me what i said ( sth like "if you don't want to teach me because i'm young, i find someone to teach me :p :)) ").

I kept frame and i didn't show jealousy, but i find this disrespectful, shit test or not. I know AWALT guys but they didn't fuck, trust me, it really isn't the case. What do you think about this, what should i do?

Sorry for the bad language
