When I was little I saw that my mom had some lacy underwear. I figured that it must be so that the man's semen could go through the lace without them having to have intercourse. I thought it was for people who wanted to have a baby but didn't want to have sex. I didn't understand why anyone would wear something as uncomfortable and itchy as lace next to their private parts.
