According to urologist David Kaufman, this is the “number one cause of post-coital urinary tract infections.”
“Bacteria have tiny pilli that act as Velcro hooks, which allow them to attach themselves to the urethral lining,” he told Yahoo Health.
If the bacteria isn’t dislodged, it can make its way up to the bladder, where it quickly reproduces and grows (which is what causes all the ouch).
So, what’s a girl to do?
Kaufman recommends waiting for a post-sex whiz. The idea is that you’ll have enough urine stored up to create a strong stream to flush all the nastiness out of your system and reduce the risk of a UTI.
But (of course) it’s not a guaranteed fix.
Some women are more susceptible than others to developing infections, as their vaginal opening is positioned closer to their vaginas, Kaufman explains.
For these peeps, it’s best to avoid using excessive lube, sex toys and always ensure you’re wiping front to back.
