lol - my T asked about sex only in response to bringing up a past romantic/sexual relationships. We didn't go into detail. I think the Freudian type theory explores a lot about sex. And we can gain insights about ourselves from our sexual fantasies, some believe. I'm thinking of this differently than CSA....though they can be related.
But I don't have a problem discussing this sort of thing. I do think I would be uncomfortable at first, but not unwilling. How would you even refer to sexual acts or body parts when discussing lovers or masturbation? Do you reference words in the same manner as you would a boyfriend/girlfriend/spouse - or would you use clinical terms? Funny to think about, but now I'm wondering.

How graphic would/should the words you choose be?
I suppose if I were talking about CSA, I'd use the more clinical terms.
I don't know about references to lovers or masturbation though! gravvy??
It's understandable to be embarassed. I think, though, Ts - if they are experienced - have heard it all. Just personally never got "there" with T yet..but thinking of many past discussions with my OBGYN, I don't get embarassed...can you think of it that way - as if you were talking to OBGYN? Would that help lighten things up?
