If you're in a long-term relationship, you probably think you have a pretty good idea of what makes your partner come. But if you're under the impression that your mate is having an orgasm every time you have sex, you might be mistaken, my friend.
According to a recent study out of Brigham Young University, just 49% of married women said they consistently experience orgasm during sex, compared to a whopping 87% of married men.
The study looked at data from 1,683 heterosexual newlywed couples. The men and women were separately asked about personal orgasm frequency, their perception of how often their partner orgasms, and their relationship and sexual satisfaction.
