Well for there to be 'too kinky' there needs to be someone in a position to deem certain kinks as 'too kinky.' To the best of my knowledge no such person exists. There isn't a standard that you have to meet to be kinky nor is there a limit that you can't exceed. There are all sorts of kinks out there. I have mine and you have your's as well as everyone else out there has theirs. We may have some kinks in common we might not have any in common. What is too kinky for one person might be someone else's favorite kink to indulge in. In the end it doesn't really matter. We are all one big kinky community. No sense is alienating people or making them feel bad for having the kinks that they do.
