I understand both sides of the argument. Personally, I love public humiliation, but one does have to be careful not to offend innocent members of the public for fun. I mean- I have many fantasies that involve public audiences, but I think it would be best not to act them out.
I think hopperboo is right that it isn't good to subject unwilling vanillas to lots of kinky games- but I also understand that Helena wanted to show off. I personally have a nice long chain leash that I would love to go out in public on with my Master- but I cannot think of many situations in which it would be appropriate. I think, and I apologize if I am wrong, possibly Helena had some bad experiences with those vanilla friends that understandably made her want to show off to them.
Again, I apologize if I assume too much, Helena. I just know it can be hard to draw the line between public fantasies and practical realities.
So Helena, congrats on the leash! And hopper- I agree with you too. Let's not make those vanilla's too too jealous ;-)
