Don't go, Luke! This is the internet... sometimes people get upset. And here especially, we all should know that when people get upset, sometimes it is more about what's going on with them than anything we have done. (No idea about the specifics, I haven't seen the posts in question, but patterns, there are patterns...)
Maggiemay, lots of people here have said "Go at your own pace with disclosure," and then you've come back and said that your T is putting pressure on you to tell your boyfriend about your past. Would it make sense to say to your therapist something like, I have started disclosure, I will do it at my own pace, please cut out the pressure ?
I also agree with Luke and maddog that your boyfriend may be quite nervous about meeting your therapist. What he said suggested to me that he might be worried (or joking, or just half joking) about finding out in the therapy session that HE is your problem.
Luke, sorry you're in a tough spot, maybe wanting intimacy, maybe not, telling nothing or telling too much. It can be so tough to deal with people.
If I were writing a scene between you (the you in my mind, of course, I don't really know you at all) and the girl who is interested in you (who I know even less), it might go like this:
The Girl: I like you. And I'd really like to touch you. Don't you think you want that, too?
Luke: Part of me does, and part of me doesn't.
The Girl: I think I know which part does.
Luke: Yeah, kind of. It's more complicated than that. There are parts in my head that feel differently. And even that part might be ambivalent.
The Girl: Why?
Luke: It's hard for me to talk about. Do you get upset hearing about stuff like starving children on the news, or those girls who were kept prisoner in a basement for years?
The Girl: What?
Luke: Some bad stuff happened to me. I'd rather not go into it right now.
The Girl: You can tell me.
Luke: Maybe I will, but not now. The thing is, parts of me are kind of, um, twitchy. Sometimes things freak me out. Things you would think were just normal. Sometimes I don't want to be touched. Sometimes I need to be alone. If you're doing something and I ask you to stop, can I trust you to stop? Without asking questions, or arguing, or getting upset?
The Girl (thinks about it): I guess so.
Luke: It's not about you. It's really hard for me to ask for what I need. If you want to be close to me, it's going to be a challenge. For you and me both. I may do things that you don't understand, and that might hurt you. Do you like a challenge? Because if you just want a nice, normal guy, I'm not that guy.
The Girl (she's not so flirtatious now, she's more serious): I'll give it a try.
