"I am attracted to males. Male attractions don't limit age.And I mean, who doesn't know that they're beautiful?"

oh yes that sounds like me too.

but, getting back to your brother: I think it's a big issue and I don't really believe you when you say you don't care. I reckon you're really angry and it's tempting to dress that up as not caring because its a way of dealing with it except it doesnt deal with anything and you need to talk about it with someone much much more.
