This guy I'm seeing said this to my gay brother

I'm seeing this guy. We aren't dating, just talking and having casual sex. He came to hang out at my sister's house. My brother was talking to me about this guy he's talking to and this guy goes "Oh you're gay?" My brother said "Yep". The guy "You don't seem gay." My brother "What does a gay person seem like besides liking dick?" Him "I mean I'm fine with gay people as long as they don't flirt with me." My brother "Don't worry about that. You're definitely not my type." The guy in talking to "........... What's that supposed to me?!" My brother " Nothing. Just I would never date you " The guy"Well I know a lot of gay people who would want to date me!" My brother "Good for them?" The rest is just him being butthurt about the whole thing.... He's lucky he has a good dick 🙄
