You have to feel comforatble with the T in order for therapy to work. That said, if you really can't get a male T, talk with the current T about how you feel about femal T's. Maybe you can find a way to get more comfortable with her.
I understand your feelings. I avoid all female docs and T's at all costs. Of couse, I've never really liked most women. I do have a few close female friends, but find men easier to get along with.
