sounds like a classic closet feedee/fa who is torn between his desires and what he thinks is "right"

Maybe you could try setting his desires free? Introduce him to this whole world which you already know about.

A space alien; I like it. Random yet hill-airy-ass as a poke of sarcasm; second what they've said already. He's so indoctrinated that he's basically fighting it out in his head; while having sorted myself out on being as I am was a thorn, having no back-up made me totally sure when I found my thing that that was it. Unless he starts to get on a bad or destuctive track-towards you or himself, I'd just let it play out 'til he settles the matter for himself.

I'd respond with things like "and?" or "so?" Obviously he is saying it to get a reaction from you, you should try play it back on him and see if he will say what he clearly wants to but is waiting to see how you react first.

Did that make any sense at all? lol :S

Nah, 10 months isn't enough to instil preferences in someone, although may be enough to reawaken ones which were buried due to not being "normal"...
