Didnt someone just say post this in the womens area because you know all of us guys are going to say why shoukd you be charging extra? Its not like you are using YOUR vagina or anything. Your raping someone with a piece of plastic . Hell i think most would see it as a time to get some revenge for all thise black guys that try to beat the pussy up . It less wear and tear for you but you want to charge more for it . Great idea .
But it is not your thing so just dont do it and save a few assholes some groef .
