I agree with everybody that there's no right or wrong answer here--it's just what feels most comfortable for you. But as Karrebear said, it's probably going to take more than a one time session to work through this. There's also the possibility that it will reflect on other issues you're dealing with in ways you can't predict right now. As Jeans said, unless you have a strong feeling one way or the other, it might be best to give your male T a chance and see how it goes. My T was male, and it was fine when the issue came up (not why I'd chosen to see him). The process of dealing with such a memory can put great demands on trust that aren't evident at the beginning, so if you have a solid trusting relationship with your male T, that can be really helpful.
