Why are some orgasms better than others, even when there’s no obvious reason for a difference in quality? A new study has proposed an explanation: A woman’s orgasm helps her determine how good a partner the other person will be.

In other words, the stronger the orgasm, the more eligible the bachelor.

By surveying heterosexual female college students in committed relationships (and it’s worth noting that only heterosexual relationships were examined), researchers at the University of Albany looked at whether orgasm intensity, frequency, and sexual satisfaction are determined by a woman’s choice of mate.

The researchers found that the more frequently the women orgasmed, the more intense the orgasms were. What’s more, the “ideal” mate — someone who causes plentiful, and therefore powerful, female orgasms — is funny, highly attractive (with broad shoulders, specifically), self-confident, and has a high-earning family. Yes, you read that correctly: Women have stronger orgasms if their partner is rich.

The researchers said that “sense of humour not only predicted [a man’s] self-confidence and family income, but it also predicted women’s propensity to initiate sex, how often they had sex, and it enhanced their orgasm frequency in comparison with other partners.”

Now, this doesn’t mean you should start pining away for a broad-shouldered heir with a rapier wit, but the study does remind us that there’s more to sex than physical performance. Or maybe it’s a message to all the men out there in committed, heterosexual relationships: If you’re trying to please your significant other in bed, consider focusing less on technique and more on your joke delivery.
