The way you feel is generally why one is not supposed to have two T's; it's just confusing and can cause you to feel guilty, etc. I did that once; my T was away for a really long time (2-3 months) so I hired another, online T for a completely separate, almost non-psychological (a recurring dream theme) purpose. But, when my T got back, I still had the online T and it was awkward "firing" her.

We can only work one-on-one. So no matter what, having two T's will be confusing because one can't know where/how to focus and get continuity. I would tell your T you saw the other T and why but not yet discuss your erotic feelings in detail with him yet if you don't want to. But perhaps this whole experience will be a help to you (since you were a little able to talk about them to someone else) and get you started more in a direction you ultimately want to go?
