One of my therapists was a LCSW and deals primarily with sexuality, sex, impotence, and GID, along with other things. The second was a Ph.D in psychology and did general therapy (marriage, divorce, personal stuff) as well as gender issues.
If you're working through gender stuff it really helps to have someone familiar with the territory and standards of care in your corner. My first therapist (neither of those mentioned above) was great at general stuff (life stress, divorce, etc) but when i came out to her she was clueless on gender stuff and was NOT helpful (back in the closet for you!!) Right.
