Your T is an arse, and doesn't get the wider world.

We live in a sexualised culture. So talking about sex a lot is the norm for both genders, not just men. Provided that a desire for sex does not override your other activities, then fine, be sexual.

As for age, well I'd imagine most younger people view porn a lot, or make sexual jokes. Whilst Ts may disapprove because being "mentally normal" is about some conservative norm (lol..)

I don't mean to hijack your thread OP, but then I have had similar issues with therapists before so I can relate. It seems they hate modern norms, and I don't see why doing as the many do is a "pathology".
