Not listen/keep asking for something you don't do!!
I recently stopped doing anal and when asked by a client I used to see a lot for only anal, told him when I was working but that I was no longer doing anal.
Cue texts of thats a waste of a lovely ass, can you make an exception for me, would love to enjoy your ass again, do you have a price that would tempt you?
It isn't about money it's a personal choice, go and find someone that offers it!!
