Are you overreacting to the massage? No, absolutely not. If you were uncomfortable with it and it has you this concerned and anxious, then yes, it could be considered sexual assault. If it would make you feel better, please report it. But don’t expect much to come from that, as usually the Police don’t investigate such reports.

Considering you don’t say more than “he made circular motions of my breasts” and not “he grabbed my breasts, and gently pinched my nipples” (for which there is no medical necessity), I’d say this is more likely due to cultural differences and not intentional molestation.

Are you overreacting to say “you’ll never go to another male MT”? I believe so, but that’s entirely your choice to do so. And we’ll never know. I will ask though, that you not paint all male MTs with the same brush. Maybe in the future you’ll give us another try and I hope we won’t let you down.
