if youre apprehensive to tell him, then you have some communication issues, and that just isn't good. might want to start working on that. better to come clean, and have a trusting relationship, rather than a devious and secretive one. also, if you tell this nice little chruch boy that you have a boyfriend, it would give a better idea of his intensions as well. not telling him, as mentioned, is kind of putting yourself in an iffy situation; aka a slutty one. some guys can be lead on, and lead him on, and you might be in more than you bargained for. but he is just a kid, so whatever
