curiouser and curiouser

So last week, i walked into my local book store with two friends, knowing full well the book I intended to buy. I casually glanced at the counter and noticed two (rather shy slightly nerdy looking) young men behind it, I already began top dread the thought of taking the book to the counter to actually pay for it. I go straight to the biography section, knowing (thanks to the advice of a friend who also works for the same franchise of book shops that this is where the book would be) and it dawns on me, the book is not there! So I sheeepishly move to my usual horror section, then on to the graphic novels and finally manga before after nagging from my friends I ask one of the young men (both of whom are blatantly younger than I am and considering I'm 22 I begin to get steadily more and more embarrassed about asking a seventeen year old about thiss particular book). I ask the young man where I might find Girl with a One Track Mind Exposed by Abby Lee, the sequel to her best selling book, Girl with a One Track Mind. the young man finds the book for me and a purchase it, admittedly making a few jokes with my friend. Upon leaving the store and heading towards the pub for a well deserved pint (or two) after a lot of shopping, and a though occurred to me. Why should I be ashamed of this book? Surely that is the point of the book isn't it? I mean why is there such a stigma surrounding women enjoying sex? Why is it seen as such a bad thing or a taboo still?
