Ladytiger, I am far from an expert at these things but here my are thoughts. If all you want to do is get vaginal dilators and practice without talking about feelings, then why even bother getting a sex therapist? You can buy them online yourself...I googled and the very first things came up was a set for sale ($44). I would think a sex therapist (or any T for that matter) would cost more than that. https://www.vaginismus.com/products/dilator_set

However, if you are having sexual issues, then my guess is that working through those emotions would be necessary for you to relax enough to allow the dilators in. In which case, I would think a therapist specializing in trauma/PTSD would be a better fit.

I wish you the best with whatever route you choose.
