@jesyka I am sorry you have a massage therapist who does not seem to have very good manners and client relations.
How do you feel the next day after the massage? Your body may tell you how beneficial the massage is. If your body is hurting the next day, that could be an indication that too much pressure is being applied.
For me when I do self massage and find a sensitive area, I keep massaging that longer but not necessarily harder. I let my hands find what my body needs. For me the pressure is the point where it is still feeling good but almost painful. I find massaging myself is the best way to get the right amount of pressure or finding someone that does not overdo the pressure.
Hope you get the support you are looking for.
