You are not a "sicko" or "freak". What you did was tremendously brave. Many people have these feelings about their T's and the configuration of genders, female w/male T, female w/female T, etc...doesn't really seem to be a factor in experiencing this. Many heterosexual married women can develop sexual attraction to their female T, in addition to the maternal and curious feelings that you are experiencing. It can be very confusing and alarming but you have handled it in the best way by talking about it. It is perfectly normal to feel afraid and overexposed after disclosing something so personal, but as you work through it with your T, hopefully those feelings will start to subside. Your T sounds really wonderful, supportive, and open.

I don't seem to have a filter with my T and I have felt the same way you are feeling now.
