We prefer manly men

While fertile, we're tempted by testosterone, a study published in the Hormones and Behavior journal found. This means that during ovulation, we're looking for a fling with a manly man rather than a long-term partner. So we want to reproduce with a guy with chiseled arms and a great jawline and then settle down with someone who will never leave us. Come on hormones, work with us here. This is totally unfair.
