Breasts might seem to increase after starting a relationship due to coinciding developmental stages (puberty), weight gain from lifestyle changes (comfort, less stress), hormonal shifts (like pregnancy/postpartum), or temporary swelling from sexual activity (blood flow/oxytocin); however, sex itself doesn't cause permanent growth, with actual changes usually linked to hormones, genetics, body fat, or life events like pregnancy.

When does breast development start and stop? In general, breast development begins between the ages of 8 and 13. A girl's breasts are typically fully developed by age 17 or 18. However, in some cases, breasts can continue to grow into a woman's early 20s.
