Paul is right; you have to stand firm and refuse to show any nudity or sex acts in free chat. It’s just like that old adage: Why buy the cow when you can get the milk for free? I’ve found it best to tease customers when they start talking about how they want to see this or that in free chat. When they start asking if I do anal, for example, I’ll say something like, “Well I’ve never done it before, but if you come private with me, I’ll try it for you.” Sometimes it works, sometimes it doesn’t.
