I, personally, wouldn’t ask such questions because this is about their private lives. I would think it's none of my business so would respect others’ privacy too (Ts included).

That being said, it is not wrong for you to ask but be aware that they might not answer, for whatever reason. i would weigh in how hurt/upset you’d be if they refused, before asking. Would also be interesting to analyse *why* you’d want to know such personal details - which they might want to discuss with you.

I would most certainly not judge a T who doesn’t respond as a bad T though. Everyone is entitled to have their ‘secret garden’ - being a T doesn’t mean one has to be transparent.
