Ok, if you don't mean sex, Gopher, then, yes, I have hooked up with many people from DV and DS. All of my experiences are very pleasant and everybody is normal-looking (ish) LOL. Some of us still meet in person to this day and I keep in contact with a few handful.
My brother met a girl from LavaLife and they are happily dating. It has been over 6 months, I believe.
