tkoss, That's something just to be discussed with the lady during negos. There's no one size fits all answer in my experience.
I can easily understand that. A guy comes in that is clean and good-looking and asks the lady if she kisses and she says "yes". Later a guy comes in with rotten, stained and missing teeth, asks her the same question and she says "no."
That's why it may be best to not give too many details about a lady, especially if you want to keep seeing her. She always reserves the right to say yes or no.
Actually, I give these women a lot of credit for what they are willing to do with people that they don't even know that may not be very attractive, or pleasant to be with. I could never do it.
