byronnnI meet people from here all the time in real life, but I usually attempt to cultivate a friendship first and see if any chemistry develops that might warrant further exploration.
I can't speak for anyone else, but on the occasions I get messages from total strangers that essentially communicate "hi, I'm horny and you're closeby - let's fuck," I tend to classify that individual as A) rude and B ) desperate - neither of which I care to idle away my time with.
My point being that if you want friends to have some casual fun with, treat them respectfully and present yourself the same way. As the old saying goes, you only have one chance to make a first impression . . .
