It's one of the most repeated tips in women's health: pee after getting intimate. And there's a simple reason behind it.
During intimacy, movement can push everyday skin bacteria into the urethra, the small tube where pee leaves your body.
Emptying your bladder soon after helps wash those germs out before they can travel up into the bladder and cause a urinary tract infection (UTI).
Women are more likely to get UTIs because the urethra is shorter and sits closer to areas where bacteria live, so germs have less distance to travel.
Two easy habits: try to pee within 30 minutes, and drink enough water so your body has something to flush with.
