I think that we are all professionals in our own way, so for me,looking for professionals can open it up to anyone in their own right.
We all get people from outside our stated bounderies. You have the choice to reply or not. I wouldn't call them time wasters though. They may live out of nowhere or maybe there are no swingers around their area? Or they may just be chancers like FB stated. There's always a reason.
For whatever reason, you decide whether to reply or not.
Good luck with your search
Like fanny says, the blood cant be in two places at once!
Make good use of the ignore button in the PM to make sure they dont bother you again.
Ssshhhhhh! Even my eyelashes hurt.
Ah, well that's where I went wrong - I'm stupid and illiterate.
