Has anyone here ever accidently met a relative, friend or coworker here?

Fuck no. That'd be so awkward... and maybe hot, too.

I often wondered about a close friend or even a family member finding me on a chat site, I know back in the mid and late 90's on Yahoo chat there were so many in the men's chat rooms it would have been easy to have someone find you there an snoop at what's going on. Any more I really don't pay much attention to others to busy chatting and ready great stories.

no but at this stage of my life it would not be a big deal to me.i am not willing to pretend i don't like the thing's i like or claim i like things that i don't like .i am who i am.to to old and to set in my way's to try and be anyone other then who i am

To answer the OPs question, I never met anyone I knew here, but in years past I sometimes ran into a co-worker or friend at an adult book store or gay bath house who would have the classic comment, "What are you doing here??" My stock answer was always,"the same reason you're here!". That would kill the embarrassment for both of us and life went on in secret. In my younger years I would have lost my job for being gay. Today it's almost a non issue.
