My mom loved Joanna Lindsey and I got the first 4 books of Clan of the Cave Bear from my aunt when I was like 12. I asked to borrow a book, she said take what I wanted off her shelf and bring it back when I was done. Several days later my aunt noticed which books I had taken, and told my mom.

My mom asked me if I had any questions, I asked if girls really liked sex that much, & she told me that they do, and that was pretty much the conversation. Then a year later I got a bunch of Stephen King and Anne Rice from my cousin and I grew into the sex positive weirdo I am today

Clan of The Cave Bear... there's a book which would need all the trigger warnings...
