I know I’m going to get scolded for this... so I’ll first say that I’m truly sorry for the poster’s experience.
I would like to emphasize the importance of clarity and saying “NO”.
This whole massage/masseur thing is complex, specifically because the MTs have to give and read queues from the client, especially with more sensual aspects of massage, when YMMV is involved.
With a single MT, he has a variety of clients, some who probably are begging for the massage to go into full on sex, others who want none at all, and others who want something in between.
I’ve had instances where the massage got erotic, we’re both oiled up, and he started “knocking at the door”, and as that door was opening up... I immediately locked that door up “kegels”, lifted my head out of that headrest and told him “no thanks”, and the massage continued and was a lot of fun.
I’m not at all blaming the victim, but I want to also make clear that there are two sides of this interaction... this MT may have been reading your queues as passive acceptance...
It’s easy to call someone a rapist because you didn’t want it... but how are they supposed to know you didn’t want it, if you didn’t tell them “No”?
Again, I want to reiterate that I am in no way shaming the poster.
