Have you ever talked to a therapist about chastity?

I would suggest that you discuss, in general terms, the idea of chastity and even potentially relinquishing control with your gf before raising the topic to the counselor. There's no need to hit Her with a surprise in front of a 3rd party. IMHO.

 

When looking for a PTSD therapist I asked if they were LGBT friendly then asked if they were BDSM and kink friendly.

The one I would up working with I spent the first few sessions explaining my relationships and kinks at a high level. I didn’t go into details but it was really a primer for her to understand my bisexuality, my kindliness, and the complex relationships I was in.

We don’t need details. But if they were relevant then I’d be fine going there. Like others I am cautious to respect her. But I’m also more open than most in that I’m not afraid to discuss anything. So I judge based on the discussion and what we are working on. And how I’m doing.

So my suggestion is ask why you want to share. If it’s relevant then bring it up on a mature and respectful way. If not then don’t.
