My guess is he wishes you'd never told him!
If he feels like the rest of us living in 'normal' land (ha, yeah right) then he's uncomfortable with what having a CD as a friend means about him. He's probably having all the same thoughts us wives have - are you gay (this will really be freaking him out), are you transexual, are you going to hike about town with him in a dress.
These thoughts will be scaring him no end, and given he's not your SO, only a friend, he may never feel the need to have these questions answered. He might just close the door and walk away from what is to him a very awkward situation.
I really do think this information shouldn't be shared unless you're ready to lose people, as our side of the fence isn't much easier than yours. We really have to weigh up what losses/issues we face when embracing what is deemed out of the norm. We too can lose jobs and friends and family just by association and while this isn't fair or right, it's reality. Sometimes ignorance really is bliss, and while many here might feel better unburdened, friends and family don't always appreciate the shift onto them. Believe me, once we know, the weight of this information can feel so heavy we want to discard it altogether, even if that means giving up a friendship or marriage.
Good luck x
