If you suffer from frequent urinary tract infections (UTIs), urinating after sex can prevent these infections from happening. Think of it this way: During sex, there’s a lot of fluids flowing back and forth, in, out, and around the genital area. With all the movement, some bacteria can creep into the bladder and sit there and multiply. This could lead to a bladder infection. Some women develop UTIs quite frequently just from sex. In those cases, a dose of antibiotics after sex may be necessary to prevent the UTI. Other preventive measures include drinking plenty of water to flush out the system, cranberry juice, and urinating after sex. Although it may seem like a burden immediately after the sex act, there’s no time requirement and you can wait until you actually feel like urinating. Have you noticed a difference with cranberry juice?
