A girl came running home to Mommy, crying.
"What's the matter," the Mother asked, concerned.
"Bobby said you show me yours and I'll show you mine and I said OK, and he showed me his, but I didn't have one," the girl cried, looking distraught.
"Oh, honey," the wise Mother replied, "don't worry. When you're old enough you can have as many of those as you want."
That old joke answers this question for most of the ladies, I'd hazard a guess, as well as anything.
