So basically we were talking about my plans for the future, I'm a student and she knows that this job is just temporary for me as my dream job is something different, which I'm studying thowards. So she asked me something like if my future job can coexist with my escorting past (in my mind). For me, it was like a slap in the face because I knew straight away that she suggests that escorting is somehow immoral. I asked why she asking me this, and she basically went silent for a few minutes trying to rephrase this question to not offend me. Then she said that if I think I will be able to still work as an escort and work in my future profession. I knew she didn't mean that in the first place because she knows that I'm not gonna work as an escort after I finish my studies. Then she said that working in healthcare conflicts with being an escort. When I will help people get healthy in the future job it is conflict with the fact that as an escort I'm risking my health to STIs. And then she continued to imply by further questions that I'm scared or should be scared of STIs...
What the actual fuck? I feel betrayed as I thought she is sex-work friendly. But now I feel that she basically thinks that all escorts are full of STIs and that this job damages me mentally and somehow marks me that I won't be able morally to have any other job in the future. But maybe I misunderstood her?
Should therapists even ask this kind of question out of the blue?! Why does she feels like it's ok to ask those questions if we haven't even spoken about it...
I could tell you what I think, and another poster could tell you their view. But we would be both guessing. The only way you can really get to the bottom of this is by arranging another session and asking her directly about what you has said. I suspect it’s a simple misunderstanding. I think you are projecting many things onto her words, hence the misunderstanding, but also, given your reaction, maybe you need to explore this topic anyway as it has clearly struck a nerve. But, at the same time, she is projecting her fears of violence towards sex workers onto you, something that is quite natural given what you have shared about your experiences escorting. However, she should be able to rein that in and not tell you that she worries about you disappearing/something untoward happening to you.
If up until now you have found working with this therapist beneficial, I urge you to talk to her about how she has made you feel - this is so important. Chances are she will know she has inadvertently got it very wrong. It will also be useful for you to lay out boundaries with regards to sex work and make it very clear that all sex is open to an element of risk, and that as an escort, you take utmost due diligence to minimise any exposure to STIs that will compromise your (sexual) health.
Does she think sex work is immoral, and has she said this to you directly? Probably not. And yes, a therapist can ask questions out of the blue if they are relevant to the conversation. Also, and unfortunately, therapy can be grossly uncomfortable at times.
In terms of sex work affecting your future career, it is possibly more for practical reasons she is mentioning this rather than STIs. How your two careers/these two facets of your personality will co-exist is an entirely valid question. Escorting full-time is very different work, not to mention financially. How will you feel earning less money and potentially working longer hours for less pay. Your standard of living might well drop. How will you feel about that? I am sure these is what she meant to explore with you rather than the avenue taken. The only way you will find out is if you talk to her.
