It is an interesting question since they are obviously either making it totally up or creating a fake persona to throw people off the scent (knowing full well it's obvious).

Lets go with "throwing people off the scent"

So pop-psyc to act gay but not be gay would rule out many cultures, genders and age groups.

So I'd go with they are a hetrosexual man, late 20's to early 30's. Western upbringing in an English speaking country.

They chose Tider over Grinder, because that's part of the story, the surprise. But they could have just said date, hence I think they are reasonable mature. It's a little clever.

Given they chose a Australia actor, I'd guess they are a New Zealander.
