I have this weird vice with talking to girls in person, when a friend tells me exactly what their vagina's look like. Especially if there's some sort of special treatment, like a weird smell or a perfect landing strip.
I just can't look them in the eye without wanting to talk about it.
I know what you mean, if i'm in a situation like that my internal monologue is like...
"Yeah, i'm thinking about about your pussy, you don't know it, but i am. thats right girl, i have info on your snatch."
But they don't know, so it's cool.
