Most women use birth control to prevent pregnancy—but it may also shape who they’re drawn to. Research suggests that hormonal contraceptives can subtly shift romantic preferences and relationship dynamics.

Normally, a woman’s hormones fluctuate throughout her cycle, affecting mood and attraction. Birth control levels out these changes, which may lead some women to prefer partners who seem more stable or nurturing—rather than overtly masculine.

Some studies have found that women on the pill often choose less traditionally masculine partners. After stopping birth control, many report a noticeable change in attraction. One woman even shared that she divorced her mild-mannered husband after going off the pill and later married a more ambitious, masculine man—someone she felt better matched her natural instincts.

While birth control is highly effective at preventing pregnancy, it’s worth considering how it might also affect your sense of attraction. Understanding this could help you navigate relationships with greater self-awareness.

Interestingly, research also shows that men and women often disagree on what makes the “ideal” lip size—another reminder of how individual preferences can be shaped by biology and perception.
