So he is making me feel a little uncomfortable..? for girls mainly?

Hey hon. Ok the best thing to do is talk to him. Don't lose your temper, just be clam and let him know that it makes you feel uncomfortable and ask him to stop. Some guys don't realize that it can make girls uncomfortable or is offensive, because some people eithyer don't tell them or they don't mind. It depends on the person. The point is that you aren't comfortable with it and that's what matters. If he says he was just joking, you let him know that you don't think it's funny and you really wish he would stop. If he's your friend then he will understand. If not then I'd stay away, because if he continues that is considered ual harment which is serious and can get worse. Just make sure you're in charge. If it persists after you talk to him, I would tell an adult. A parent, a counselor, anyone you can trust and tell them how you feel and what can be done. But like I said talk to him first and like I said he may not realize it's hurting you. Most guys joke around like this a lot and that makes them think it's ok. I hope everything works out.
