No... I didn't know T's orientation when I went to see her (dad found her and made my first appointment) and she turned out to be straight and married - which is fine. It is/was a non-issue. I didn't even know my own orientation when I started therapy with her. I now realise I'm gay, and while I'm happy with my T and she's been totally understanding and supportive regarding that, if I were ever to look for a new T it might be something I'd consider.. maybe a gay T would better know the issues I might face and how to deal with them... I think I'd always see a female T at least - gender seems like another barrier to me, I don't tend to connect well with men.
