Need help

Kenzie

So this guy in my class won’t stop asking me for nudes and I don’t want to get and adults involved cause who would and I’ve even got a friend of mine to act like my ‘boyfriend’ to make him stop but he didn’t! Plz help I honestly don’t know what to do. Sometimes he asks in front of his friends to try and show off and I don’t know what to do to make him stop. HELP
