I would not see two therapists, but that is about me, not because it is somehow a bad idea or improper, but because I feel that intimacy is a limited resource. It's the same reason why I only have one spouse and no other lovers-- I don't have any issues with people who choose otherwise-- and why I only have one child. I have just so much ability to share myself and what's going on in my life, so much openness I can tolerate, only so much interpersonal risk I'm willing to take. If I'm being as intimate as I possibly can in therapy with one T, I'm not going to have anything left to share with the other T.
