So basically they don't let you forget it. I wonder if most people have a slightly embarassing story that their family never let them forget? To laugh about at family gatherings.Only very vaguely, but it gets brought up at family gatherings every few years.
It is weird isn't, and your reaction was healthy, but when you are young this whole world that the adults know about; sex and human bodies especially those of the opposite sex are a complete mystery to children.
But look at the world now, not much is a mystery, on the Web or in games.
