The good news when it comes to a post-sex hygiene routine, is that there is no magic answer- you do you! Keep it simple and do whatever you feel comfortable with.
Contrary to a popular myth, urinating after intercourse will not help prevent UTIs, so you don’t have to jump up to the bathroom. Make sure that when you do wash, that you wash externally on the vulva with gentle soap and water, no need to get aggressive in the vaginal canal. If any toys were used, make sure to wash those with soap and water prior to reusing, as these can harbor bacteria.
