What’s more taboo than sex (and by association, sex memes?) If you’re an American, nothing!
We’re still remarkably repressed when talking about sex, which is frustrating to live with but makes for some damn funny memes.
So, my fellow Americans, make sure no one is watching and enjoy. As for the rest of you, enjoy your sex memes. Call your mates over and have a wank, or whatever it is you people do.
