This post got me to stop lurking and sign up. Aspartame is 200 times sweeter than sugar. The body does not metabolize it. It is peed out. When I book a session I ask the Mistress if she minds refraining. I've never received a negative respond. The way I look at it is that I'm spending a lot of money for the experience. It isn't an unreasonable request. You wouldn't be out of line to ask.
