I think your T is merely obsorving your boundaries around the subject. My T hasn't asked about it, either (3 months in), though the subject of sex has come up in some minor ways. Pretty sure he doesn't ask about romantic relationships, because I am not in a place to have one, not because I am inherently unattractive. I'm sure it's the same for you, but maybe you could ask? You could perhaps state that you don't want to talk about it, but were wondering why the T hasn't asked (?)
