Most of the responses were of the banana-and-watermelon variety, à la Homemade Sex Toys. But not all. One engineering student admitted in the Sex Drive forum that he has developed a new interface for an Xbox vibrating pad. For what purpose, he didn't say.
Still, it quickly became clear that most of us have reached for something other than ourselves and each other in the quest for sexual pleasure. In my early teens, I discovered interesting things to do with the stream of water pouring out of the bath tap. (Yes, jazz band alumni, that is how I arrived relaxed despite having to get up at the crack of dawn for our sadistic before-school practices.)
It was years before I learned that I was not the only girl to discover the possibilities of running water. Hairbrushes, the shower massage, a sock, egg whites -- if it can engulf, massage, penetrate or lubricate, someone has tried it.
