I was thinking age, geo, culture etc.
Ah, gotcha. I don't know. I'd like to think as society moves along we smarten the fuk up about things, but I don't know if that's true or not. Culture affects pretty much everything. Western society is fairly open (as in minded) but still has a hell of a long way to go, but there are sub-cultures within it that are pretty closed off.
Geo? I don't know. I guess I always figured where it's the coldest people are going at it like bunnies, lol. Guess that doesn't speak to the satisfaction part though, quantity isn't the same as quality.
