Is it gay for my brother to see me naked?

I'm also a boy, he's sharing the same room as me, because our new baby brother is moving in his old room.

I'm 17, he's 12...
Update: No you clearly don't get it, he moved in to my room, when I'm done showering, I change. Morons.
Update 2: I don't want him to see me naked, but what other choice do I have? Change in the bathroom? No, we only have 1, theres 8 people in my house, they'll be bitching to go in.
