I am just trying to understand here - you are a lesbian, in a new job, breaking up with your partner, and moving but you wanted to talk about having sex with him to him? Did you try to explain you were trying to explore why you were having such feelings or were you trying to talk to him about getting him to go to bed with you? Did he perhaps think the sex with him was not really the most useful focus of your appointment? Did he explain why you could not talk about what you wanted to? I am a bit baffled about why you wanted to talk about having sex with him - what would the point of that have been with a therapist when you have all this other stuff going on?
Not that you have to answer me, just I truly do not understand (there are numerous things all over I do not understand - I am not saying I have to understand this either - just worried about you and wish you could/would get help)
