There are some books I think some kids should have access to in order to help them understand certain things that a parent may have trouble explaining, or that a parent won't explain, and some that shouldn't even be allowed anywhere near kids.
This book shouldn't even be allowed near kids without a parent or trusted guardian there.
I've nothing against the way some people choose to live their lives, but this is rated for 18 and older for a reason. Teenage years are hard enough without this being presented as an option.
VERY graphic and sexually explicit.
