We encounter quite a few, the usual excuses, and the classic guy wanting to meet alone.
We like to do social meets before play, that usually sorts out the fakes.
As a couple, we get a lot of quite crude messages,, and even abuse when we don't want to hook up straight away, thus the Mr does most of the initial chat online, then we set up a meet somewhere public if she is interested.
As these sites have become more widely known, sadly the desperate single males, often devoid of redeeming social skills jump on on thinking they can get laid.
Mind you, we have met some very nice singles on here, a few bi males who have joined us but the art of conversation, lack of demands for pics right off the bat are what get them into our bed.
