I think my gay student has a crush on me. He is 14 and in 10th grade, very feminine and flamboyant (likes to do dance moves in class). This is at an international school in Asia. I am straight, masculine, not into teen boys. He is also the smartest student who is great at English and all subjects. I can't control him because he manages to get under my skin. He always wants to be in my room and when I come back from lunch he's in there. Any time I pay him the slightest attention he'll take that as if I like him and it drives me crazy. I have other students to manage who need my attention but he wants it all for himself. Any advice for this please?
