What does massage therapy guideline says about sexual violation?

[Ms. A]

I just start going to a massage school very recently. We were assigned to team up with two students on each table, and give each other massage in a class. What happened was a male student from different class came into our massage practice room while I was giving one of my classmate a massage. I didn't notice that she was making uncomfortable face, when the guy student came in. I was too busy thinking about the each steps of massage that we were just taught, and I had totally forgotten about half of her butt was exposed in front of the male student. I quickly covered that area with sheet, as soon as the male student said "Don't worry, I have seen people's butts".

I apologized to whom I was giving massage to, after that incident. She was still looking very upset. I'm afraid that I maybe dismissed from the school or being sued for not paying attention to what's going on around us. I was trying to look up for sexual violation law on google, but I can't find the answer that I'm looking for. Could somebody explain the policy and guideline regarding sexual violation among massage schools?
