A urinary tract infection causing a burning sensation during peeing! Also causes a constant need to pee, and is generally very uncomfortable, can be very painful if left to fester! Is also exacerbated by excessive hardcore sex! Having a wee and a wash after sex can prevent this from happening.
Excessive fluid intake is needed in order to dilute the infection. If this fails then antibiotics are needed. You may have blood in your wee!
