The United States is obsessed with virginity from the media to schools to government agencies. In The Purity Myth Jessica Valenti argues that the country’s intense focus on chastity is damaging to young women. Through in-depth cultural and social analysis, Valenti reveals that powerful messaging on both extremes ranging from abstinence curriculum to Girls Gone Wild infomercials place a young woman’s worth entirely on her sexuality.

In The Pleasure Gap, Katherine Rowland rejects the idea that women should settle for diminished pleasure; instead, she argues women should take inequality in the bedroom as seriously as we take it in the workplace and understand its causes and effects. Drawing on extensive research and interviews with more than 100 women and dozens of sexual health professionals, Rowland shows that the pleasure gap is neither medical malady nor psychological condition but rather a result of our culture's troubled relationship with women's sexual expression.

What does it take to make sure she experiences the big O (or a few of them) every single time? When it comes to sex, most men worry that their endurance isn’t sufficient. It’s a common misconception that longer bedroom action = more pleasure. Let’s face it, guys, this isn’t the case! Most women need 10 to 20 minutes of stimulation to reach orgasm.
