Meeting someone off of Lush would certainly be an interesting event. Certainly both of you would feel nervous to some extent, as you met through an erotic story site :P but truly I would have to say yes I would. I would want to get to know them a little first, just to make sure they aren't some axe murderer or something. But I also would say that it would be a rare event. More common I believe would be meeting for talking and food. I am a very different person offline, much more uptight and nervous, as unlike online, when you're in person, its much harder to recover if you throw a stick in the mix.
