Ok, since you ask -
Up at the top of every page on this site I've come across it says: "This site is intended for adult audiences only. If you are under the age of 18, please do not visit this site."
Therefore, unless specifically stated otherwise, I conclude that all the posters are at least 18.
By that age, if you don't know the answers to some of the more preposterous questions or comments I see posted here, my most generous conclusion is that the OP simply hasn't been paying attention.
Such people are often viewed as "fair game".
I think the other reason is because this whole thing is designed for CONFESSIONS.
You tell what you've done, NOT ask how to do it.
You want advice, go somewhere else. This is for the juicy stories!
I've had a couple rude answers to my posts too. I don't really care though.
Sometimes a little advice would be a good thing.
