To them, it is a way of cleaning up the vag!na (bladder) before the s 3x, probably also to prevent themselves from urinating in error due to the intense pl3asure . The truth however is that they are putting themselves at more risk by urinating BEFORE having s3 x. Why? Well, scientists say the best time for a woman to urinate is actually after s3 x, immediately after if possible. As was explained by a New York City urologist, David Kaufman, MD, urinating after s3 x, not before, helps remove bacteria from the urinary tract, thereby saving the woman from infections.“Bacteria have tiny pilli that act as Velcro hooks, which allow them to attach themselves to the urethral lining,” Kaufman told Yahoo Health. If these bacteria are left there, they move into the bladder where they quickly reproduce and grows, leading to a Urinary Tract Infection (UTI) with serious consequences.What this means is that it is better to leave the urine in your bladder so that you’ll have enough to push out the stubborn bacteria after you are done with s 3x.
