I have a hard time talking about sex in general. I've made passing references to "intimacy" with my ex-partner but ... not so much sex. I'd like to get there but I guess I don't have that as a pressing issue at the moment.

(ETA
I will add that my Therapist made a comment once that gave me a clue as to how it would go if/when the subject did come up. I made a joke about how my phone sometimes wants to grab her name out of my contacts instead of my partners when voice texting (they both start with similar letters). So, I told My T, if she should happen to get an odd text from me about bringing home groceries, or when I'll be home, to ignore it. She laughed and said she had a friend of hers accidently send her "Sexting" text meant for that friend's husband. T used this anecdote as a way to show that she wasn't in any way flustered by other people's sex talk. I should expect any therapist SHOULD be good at talking about sex and be able to make the client feel comfortable - that is basically their job— but it's good to hear how she would handle the subject even in a round about way.

I'm gonna say if your therapist is remotely worth his salt, he'll be fine. Ask for what you need, tell him how you're struggling with it and then it'll be done.
