My T is also male. I actually feel more comfortable talking to him about certain topics like sex than I did with my ex-T, who was female (though she was my mom's age, so maybe that was related?) I tend to feel more comfortable talking to men in general (and always have). I say, give him a try and see how you feel. Like others have said, I think so much of it is about whether you click with a certain T and more about their style and personality than their gender.
