What has a woman who has sex with men want to sleep with a man again and again? What, according to sex research, makes a man great in bed? It's not what you might think. I was recently on Robbie Kramer's podcast Leverage discussing findings in my sex research. Thousands of women revealed what, to them makes a man a great lover. Interestingly, less than 5% of women talked about a man staying hard all the time; less than 2% talked about penis size, and less than 1% talked about a man having a good body. But over 70% of women mentioned one specific trait that the men who are best at sex cultivate. Whether you're dating, in a committed relationship, or somewhere in between, you're likely to get something out of this lively back-and-forth on sex, communication, polarity, male/female dynamics, and more.
