I understand. I am female and also prefer to have a male T and am in general more motivated to talk about deeply personal things to men, including sex. It's related to personal history like for others. I don't think there is anything wrong or weird about these preferences. If you feel uncomfortable, could you maybe probe into how your T reacts to sexual topics first before getting into the very personal details? Maybe even tell him that you would like to talk about sex but feel uncomfortable and would like him to help with the discussion. I think a decent T should not behave provocative in any way or make you think that he is fantasizing about you or something and would handle the subject just like any other conversations, especially if you express your concern beforehand.
