By the way I dont even know what Douche means
http://en.wikipedia.org/wiki/Douche
It's a sexual health thing. Douche bag refers to just the bag part, not the nozel. They can be used like enemas as well before bum sex fun times, you will find them on porn sets and the like and I'm sure gay men could use them from time to time, but I don't know about that side of things.
