Travel up urethra: E. Coli species are the most common bowel bacteria and are invariably present on the perineal skin, no matter how well you wipe. They will be present in any urine temporarily trapped behind the labia and get "sucked" up the urethra during terminal muscle contractions at end of voiding. E. Coli around the urethral opening can be pushed up the urethra during sex. Hence advice to urinate after sex.
