New York City urologist David Kaufman explained the idea females should pee before intercourse is one of the biggest misconceptions he has to address with patients in his clinic. He stresses that urinating after sex is important, but warns going to the bathroom beforehand is not advisable. Urinating and consequently having enough urine stored up to create a strong stream, increases the odds of pushing bacteria out after sex.
Holding on will ensure full bladder to produce a stream strong enough to clear any bacteria in the urethra. Without any urine in the bladder, the bacteria can cause an infection. Not urinating after sex can make cause bacterial to make its way into the bladder and develop into an infection. Women are far more susceptible to UTIs than men because of their anatomy. The female urethra is separated from the vagina and anus by just a small distance, making it easy for bacteria from either the vagina or bottom to reach it.
According to the NHS, using a diaphragm as contraception can increase your risk of getting a UTI, as the diaphragm may press on the bladder and prevent it emptying completely. You can do this to prevent UTI. Avoiding perfumed bubble bath, soap or talcum powder around your genitals-use plain, unperfumed varieties, and have a shower rather than a bath.
Going to the toilet as soon as you need to pee and always emptying your bladder fully. Staying hydrated,wiping your bottom from front to back when you go to the toilet, emptying your bladder as soon as possible after having sex, not using a contraceptive diaphragm or condoms with spermicidal lubricant on them.Wearing underwear made from cotton, rather than synthetic material such as nylon, and avoiding tight jeans and trousers
