That's is one of the best Threads I've seen here.
It's very easy to be very honest or dishonest in a place like this. As for myself I' honest to a certain limit. I think that most are that, as we probably all have things in the past, that we don't want to talk about.
But it probably often would be much easier to lie, to get a better result. If I see a cute sub-girl who'd I'd like to know better, I probably would have more luck telling that I'm 26 instead of the double. I think that's one of the reasons for lying.
As long as you only "play" on the net and haven't promised that the other part is the one and only, meeting living happyli ever after. Many probably will "play" with more. Which is a non existing problem for some of us.
