My 22M brother just told me 25F that he's gay. How do I react?

Hey guys, I'm 25F and I'm not good at this sort of thing. My brother is 22M. Anyways I have a gay male cousin and sister. Anyways I'm sure he could tell here and not tell our strict, ethnically diverse parents. I'm sure he's uncomfortable seeing me. <br><br>what do I do about this? He hasn't said anything else about it. I feel he's gone somewhere far because he's uncomfortable around me. Anyways I'm feeling bad about this. <br><br>How do I react here?
