I just finished the fantastic book "Come as You Are: The Surprising New Science that Will Transform Your Sex Life" by Emily Nagoski. What was most striking about it for me wasn't the science (though Nagoski does a great job at laying that out, along with the misconceptions, inaccuracies, and propaganda we've all been fed for too long.)
No, what was most striking was the frequent refrain/reassurance that we're all normal--in terms of our body parts, our desires, our arousal, our orgasms. You name it: it's variable from person to person.
And the number one enemy, what's really keeping you from having the sex life you want, is preconceptions about what's normal, or right, or what everyone else is doing, or what we're all supposed to be doing and feeling. The question, "Am I normal?", does us all a disservice. But the answer, every time is yes.
