The most casual of sexual encounters, the one night stand, involves a thrilling, spontaneous meeting between two consensual partners who are emboldened by the fact that they may never see each other again.

Why would a girl have a one night stand?

Women are happy with one night stands as long as they made the first move and enjoyed the sex. A study of 763 people also found females are more likely to regret sleeping with someone too soon, while men are likely to regret passing up casual sex. Men care less about who makes the first move.
