Does anyone else feel awkward around some of your friends brothers?

So one of my friends has this brother and he seems extremely shy he has a girlfriend but, I know they aren't doing very well..but, My friend told me that her parents like me and her parents are cool her dad is a little to nice he's a preacher and I'm not religious at all so for them to accept me it's nice(: but, one day we went to dinner without her brother(he wasn't home) and her dad was asking me questions and he started talking about (we will call my friends brother Jim) Jim and was asking me questions like,"have you talked to Jim before?" and I said,"umm a little haha" we haven't really talked but, like once or twice and its just be hey, whats up. He's always really shy and once I was soaking wet and you could see my bra so it was awkward. But, then he said to my friend,"does Jim like Erin?" and she said something like yeah or I don't know..but then we kept on talking and he said,"I think Jim would like you!! You might talk to fast for him though..haha!" haha so i just want to know what to think about this situation and do you guys feel awkward around some of your friends brothers? Thanks!
