I hate it when the pussy is dry. It's like a bad review even before you start.
Also hate when the pussy is too hairy. I don't want to have to untangle all that to get through.
Worst is when the girl acts like she is going to "allow" you to do her, or she feels that all she has to do is get naked. Like just having her be there is enough. I'm afraid that I've had a couple of those, and looking back, I should have just got dressed and left as soon as I picked up that vibe.
