coming out to siblings

i dont remember how we got on the subject, but i remember my brother and i talking about the issue of two girls kissing. Either we just finished watching a movie about it or something that had a scene of two girls kissing on screen. Of course, him being the stereotypical guy, he thought it was hot for two girls to be making out. I asked him what he thought about two guys kissing, and he said the idea didn't make him feel comfortable. I then asked him: 

"And what if I told you I was gay?"

 He replied "Nah, don't be joking around. I know you are not, so it doesnt matter." 


Then I asked him again, "..but what if I am?"

 "But I know you're not...wait, really?"

 I just keep looking at him with a plain expression, and simply told him in a matter-of-fact tone: 

"Yes, I am."    

After a couple of minutes pass, he comes back to my room and tells me:

"...uhh,... actually, I think its fine that you are a Lesbian. Its cool, you can love anybody you choose, as long as you are happy."

:)  I'm lucky to have such a supportive brother.
