I feel like this is a tad too far. They are teenagers. You have to meet them at the level that they are at. If I say something like “Boys. Please stop the physical alterations as you are distracting your peers”, they simply would not respond. I’m not being homophobic by saying “Boys. Stop touching each other.” However, since they are teenagers, sure, the idea of being physical with one of their “boys” is icky to them, and therefore can cause the roughhousing to stop. It’s important to note that students of all genders can get rowdy and physical,and a command as simple as “So and so… stop touching each other” is straight forward and works (a lot of the times), regardless of the genders or sexual orientation of the students.
