There is more to the world then Man on Top and Woman on top

I was with my school friends a couple of days back and in all the banter someone started conversation about the topic we all love :) After listening to them intently I decided to pitch and started talking about kinks and alternate forms of sexuality and suddenly everyone got interested. It was like I am telling them my personal fantasies and most of them were giving me a dazed expression on what I was talking about. When I was talking about "foot fetish" everyone was laughing that why someone in the world will do that. The explanation of the word "cuckolding' got them really uncomfortable and talk about BDSM made them feel sick. I kept going in enthusiastically when someone pitched in and said that he only understands woman on top and man on top and all this sounds so silly to him. Then was the time I realized that I had spoken too much and it was time to fall back on the chair and carry on with my diet coke.

PS: From my personal experience we are the most sex crazed society but we score very dismally when it comes to the kink quotient
