Gumtree
Not sure if this counts.

My missus read in one of her "wimmin's" mags about how some rough old slapper gets regular deep-dick action by advertising where she'll be on business and when she'll be available for a piping. I pointed out this would only work for a woman. The wife disagrees.

And so the experiment started. We placed adverts on Gumtree - one "woman seeks man"; one "man seeks woman" and one "couple seeks other", just for shits and giggles - each one stating "picture garuntees response". We then waited for the replies to roll in.

Though we didn't have to wait long. The "woman seeks man" advert got four responses within 20 minutes, which I thought was slightly strange considering we posted the advert a little before midnight on December 30th. By the morning, the inbox of the fake email address we used was stuffed with cocks, hundreds of the things. Plus some of the pictures of said love-lengths showed them being used in slightly unusual ways.

After a few minutes of checking out the weird replies, I felt more than a little sick. Not least by my wife looking at one picture and uttering the phrase "you wouldn't shag him, he's got crap wallpaper".

I was right, though. The "man seeking woman" only got "are you sure you're after a woman?" type replies. And more pictures of cocks.

I did something similar...
... and found that even the most desperate, diseased subject would elicit hundreds of pictures of cocks.

It was all strangely dispiriting.

Lezzers do it, too.
I can empathise. My post earlier on in the thread is on a similar subject.
Lesbians sent me pics of their lady lettuce.
WITHOUT EVEN CHATTING ME UP, FIRST!

Oh, the horror.

The thing is...
...these days almost ANYTHING can get flooded with pictures of cocks:

Man seeking enlightenment - unleash the cocks!

Woman seeking friendship - Dispatch the dicksquads!

Man hiring opére - Release the Krackenpenis!

I'm mildly horrified
by the term "lady lettuce"

For me picturing the cover of Cosmo with one of the article titles being "rough old slapper gets regular deep-dick action".
