Well, I wouldn't go out on a date with someone unless I had opened up to them about me in three relevant areas.

If I intended to say yes to a request, and I do get them, my usual response will be something like this.

"I'm not going to say yes or no. I want to tell you three things about myself, and if, after hearing them, you're still want to ask me out, then I'll answer. First thing- I'm queer. Second thing- I'm poly. Third thing- I'm kinky."

And if they're still happy to ask me out, then fine- vanilla or not, they're clearly worth the time
