I know this is a bit different, but just in case it helps at all: I'm a medical student (graduating with my MD in June), and I have to ask people about details of their sex lives all the time. I have never *ever* been turned on by this.

First of all, when I walk into a patient's room it's like a switch goes off and nothing is sexy. (I've heard straight male obstetricians say the same thing. Like, "yes, I very much enjoy the female form, but doing a breast exam or a pap smear on a patient is not even remotely sexy.") I'm looking and listening for things that could make my patients sick/things that cause suffering, and that takes up a lot of brain space. I'm listening to what they're saying and comparing that with my medical knowledge and trying to put it into the context of the rest of the patient's life. And I'm also using a lot of energy trying to figure out how to make the patient less uncomfortable (not to mention trying not to do anything awkward myself).

So I doubt your T is turned on.
