If you gave it some thought you could probably create a long list of things you should never do before sex but always do after.
But, apparently, going for a wee is one that everyone should know about.
The advice applies to women rather than men – and experts say that many are incorrectly doing it the wrong way round.
This latest advice comes from New York urologist David Kaufman who said the idea that one has to have a ‘pee before sex’ was a common misconception held by his patients.
Why do women suffer more from cystitis than men?
He told Yahoo that it can actually increase your chances of catching a urinary tract infection [UTI] – because a strong stream of urine after sex helps to dislodge any vaginal bacteria that might have been pushed into the urethra during sex. If the bacteria isn’t removed, it can makes its way into the bladder where it can cause a UTI.
‘[It] is the No.1 cause of post-coital urinary tract infections, also known as honeymoon cystitis,’ he said.
‘Bacteria have tiny pilli that act as Velcro hooks, which allow them to attach themselves to the urethral lining. Having a solid stream afterward is crucial since the bacteria can be hard to dislodge.’
He said that holding on will make sure your bladder is full enough to produce a stream strong enough to help clear any bacteria in the urethra.
If you absolutely must go before you have sex, drinking plenty of liquids afterwards could help you to get to the stage where your post-coital stream is back to full strength.
