Hey J! *winks*
I have... although in my line of work, it's usually people I've worked with that eventually works their way in :)
I believe that whatever works for 2 mature adults is what it is... I've met a lot of people on MBC that I've become hard fast friends with... some I've had sex with, and others I haven't... I believe how we meet really has no affect on the relationship... rather how we interact does...
Just my titty cents...
