You ever notice that gay people won't answer direct questions about their sex lives? I guess they don't give straight answers.
What do you mean here? Are you telling jokes about gay people?
I mean gays don't give straight answers.
It is a little insensitive to make jokes about gay people not being truthful about their sex lives. While the joke did have the intent just to make someone laugh, it is also disrespectful to gay people as a group.
I'm not joking about it. I see some gay guys kissing in the streets, I don't see straight guys kissing in the streets.
But an offensive joke is still offensive, and I believe you should be a little more tasteful around gay people. They are allowed to disclose whatever they want in their life, and aren't obligated to tell you about their sex life. Everyone has the right to secrecy, even you!
