In brief: Many

Bacteria multiplying in bladder.
Not urinating after sex, allowing bacteria which reached bladder ; multiply. Using bubble-bath and tub baths rather than taking a shower, severe constipation, sub-optimal toilet hygiene- not wiping front to back or holding thighs together with urinating + trapping urine behind labia, witholding urination, thongs and non-cotton underwear.
