Sex and anything related is one of the most difficult things for me to talk about to my T. However it's been a big topic because of the SA from my H. I usually keep it very superficial and don't give too many details. I also don't use the proper terms for things like masterbation, fingering, rape, etc while my T does. My T has been great so far when I do manage to talk about things, and he's assured me that people are sexual and it's okay and normal to talk about.
