Chances are, your T has heard stuff like this already, perhaps even worse/more embarrassing, so perhaps remembering this might help you disclose. I actually disclosed something last week I really didn't intend to be a disclosure, but when she reacted to it I was thinking "uh oh, this is going to be brought up again...", another one of those things where I didn't think it was a big deal, and she did (and now, all of a sudden, is too embarrassing for me to admit here LOL). Yet the things I think were big, she didn't.... I think it's all in how they know you feel about it....so let him know beforehand how difficult this disclosure is, and I'm sure he'll treat it even more respectfully.
