"I don’t know how it is for single females, but I know that for me that game is played. I get requested to send pic after pic, or video of me in “action”, and for what? So the husband and wife can have something to look at? But they can’t deliver on my request.
The same inappropriate emails that wives/females get from single guys are the same ones I get from couples. “Show me what’s hanging mister” or “Mama likes what she sees, can I see”. I get it. I get the short end of the stick. I’m a single guy, whoopty doo."
I'm going to guess that 99 out of a hundred of those requests are generated by the husband and driven by a thing I will never understand, which is how some straight men are fascinated by other men's dicks.
When I get emails from couples where the profile does not include a photo of him, I just politely decline. Same for profiles where the only photos are of a woman in pieces. Bathroom selfies or those that sport boxer briefs and a hard on get the same treatment. It's not the content or lack thereof that drives that automatic decision. I've just learned that those are markers for couples or singles with whom I won't click. So, thanks but no thanks.
Any demands in any email, even if I think the chemistry would otherwise be awesome, result in either a lack of any further responses or a yeah, never mind, turns out we wouldn't be a match.
And that's all a roundabout way of saying that instead of thinking they should give something approaching what they're demanding, you might consider that you've just been saved some time and energy deciding if they're a match, because they aren't.
