When I was at CEDU, homosexuality was totally taboo, too. I mean, even if it was plainly evident that someone was (and who cares if he was) they would never touch it. If other kids brought it up, the staff changed the topic. In fact, when two older girls were caught by a younger student, the male staff accused the younger student of lying. The funny thing was that all normal sexual urges/behavior (the ones that indicate you are alive and developing well) were demonized;we were made to rehash these experiences/feelings and reinterpret them as wrong. This really fucked some of us up. It made us question normal behavior and assigned guilt to something that should be life affirming and beautiful.
I would have respected it so much more if staff just let us be flirtatious teenagers and treated sexuality as normal and just asserted they can't encourage sexual activity because of liability concerns (pregnancy etc.). Or even therapeutic concerns (we want you to focus on yourself, etc.)
In any event, I'm sure that when some of us got out, the first thing we did was get laid.
