Women don’t understand how men can differentiate so easily between love and sex.

Ian: One of the reasons is that during sex, women produce lots of oxytocin, a hormone that stimulates a strong emotional connection. As a result, women are more emotionally integrated when it comes to sex. That’s why casual sex and hookups often backfire for lots of women. Guys produce little to no oxytocin, and can easily have sex without any sense of emotional connection. It’s sex with no emotional strings attached.
