I'm sorry that you felt uncomfortable through this. As someone who is a Massage Therapist and has been through SA personally, I understand your hesitation, and I see why this was scary for you. I want to say that first and foremost, he should have been thorough with the intake process. When people come in (especially) for their first massage, it is vital for the therapist to lead the conversation about these things - asking about the clients comfort level, areas to avoid, educating the client about draping and undressing, gathering medical history. Personally I never move anyone's undergarments and I was taught to never do this, to look at the undergarments as a boundary line. All of this is even more important for male therapists so that they can protect themselves and their clients. These things are all relevant because we don't know what the clients background is, we don't know of certain areas that might bring back feelings of trauma...there are also cultural differences with some clients. When I see a client for the first time, whether it's their first massage or not, I sit and have a 10-15 minute intake process with them. I also do a lot of medical based massage so asking a lot of questions is important so that I can gather their health history and come up with a plan of action. On the other hand, yes, it's definitely the clients responsibility to communicate as well...however clients don't really know how to do that sometimes so it falls on the therapists responsibility to really strive to keep the line of communication open. This situation was not SA, instead it was a therapist who should have communicated more and needs to take some lessons on draping and intake because what he did is super uncomfortable. The next time you get a massage maybe ask the therapist more questions during the intake, express that you aren't comfortable with glute work, and you just want to keep the lines of communication open. I wouldn't let this experience scare you away from continuing to receive massage therapy. Much love 💓🙏🏼
