What causes UTIs?
“UTIs can happen for no reason at all. That’s important for everybody to know,” Plotch says. “But there are a couple things that can be correlated or make one more susceptible. Having sex frequently introduces more bacteria into the area. The old adage to pee after sex is important.” For further clarification as to why it’s necessary to urinate after sex, doctors say that the urethra sits very close to the vaginal canal and sometimes bacteria from the gastrointestinal tract can find its way into the vagina, and then over to the urethra, causing an infection. The idea behind peeing quickly after sex is to flush out any bacteria that may have gotten in there.
