I can feel myself getting sexually aroused when the intimacy in the room is evident. For example, when our eyes meet after an honest exchange of words has been made, when I tell my T (woman, as well as me) that I love her, etc.
I see her as the mom i always wanted to have, so it's very confusing to experience that. And maybe it's true, and it's just our bodies reacting in an adult way to the child needs, but for me it's accompanied with masturbatory fantasies about her, so that makes it even more confusing to just assume it's the child needs.
I shared with her today some of my fantasies, and she was great about it, as she always is. It wasn't easy to share, but she is so open and accepting and doesn't recoil from me at all, so that makes it easier. I shared with her my need to seduce her, to have her submit to me and to give her pleasure. I view it more as wanting to balance the relationship or even turn the tables, and have me be in control and give her, rather than have her in control and give me.
Good luck with sharing that with your T. I am sure you will do fine!
