Beth was the youngest child of 3, her two older sisters were about 7 or so years older than her. While they were related, Beth rarely saw either of them, but even with this distance, they both remained role models to her.
Somewhere in between Beth’s childhood and her sisters teen years, her mother had a mental break, so to speak. Almost overnight, Beths mom became over the top, excessively, religious. This happened when Beth was about 6 or 7. It’s what drove her sisters away.
Throughout school and brief interactions with her classmates, Beth picked up on the fact that she was pretty sheltered and missing out on a lot of experiences and knowledge (of the sexual nature) that others her age were privy to. This of course was because of her mom, but that didn’t become apparent to Beth till years later. By the time Beth was a sophomore in high school, she hadn’t even had a kiss before, though never from lack of interest or desire.
