Sleeping with the wrong person may feel like a harmless choice in the heat of the moment, but its impact often lingers long after the encounter has ended.

Intimacy, which should ideally bring comfort and closeness, can instead leave behind scars when shared with the wrong partner—scars that stretch far beyond a single night.
