Its a wild and whacky world.
And a matter of personal taste. To me its boring to recieve, distastefull to do. So it's bad sex for me. I have dated a few women of exactly the opposite tastes (well, one).
It's extremly lucky for me that I have encountered so many fine ladies who shared my preferences. And No, 'regular sex', its not boring, it's varied and playfull and loving and fun. But I'm simple, maybe my girlfriends and wives the same.
Is this really taught in schools?
