But why? Kansas-based gynaecologist Leslie E. F. Page told Women’s Health, “When the vaginal tissues have been lubricated, swollen, and rubbed against during intercourse, it changes how that tissue reacts to the environment. Primarily, you run a much greater risk of infection.”

Lathering up

If you feel the need to freshen up post-sex make sure you don’t use soap. While it might sound like a good idea, lathering up your nether-regions can actually do more harm than good. Not only could you have an allergic reaction if your skin reacts differently to the chemicals in cleansers, but “using soap can lead to vaginal irritation and dryness,” says Robert Wool, M. D., ob-gyn.

If you do want to take a shower just make sure you use plan old water, “The vagina is a self-cleaning organ, and needs to be treated very, very gently—if you wouldn’t put it in your mouth, you shouldn’t put it in or around your vagina,” Page says.

Forgetting to pee

It turns out that going to the loo after a bonk isn’t an old wives’ tale after all. During sex bacteria can get pushed into the bladder, “This can result in post-intercourse bladder infections,” says Wool, “You can have some snuggle time, just empty your bladder within an hour of sex.”
