It is possible to have sex during urinary tract infection, but it is generally not recommended to have sex during the infection period. Because during the infection period there is frequent, urgent and painful urination, sex can easily aggravate the degree of infection leading to lower satisfaction of sex life between couples and also easily lead to a feeling of disgust for sex. Especially for women, during the period of urinary tract infection, having sex can easily lead to the retrograde entry of bacteria from the urethra into the urethra leading to the aggravation of the infection. It is a very common cause of infection for women to have sex under such circumstances. It is recommended that the best way to have sex is after the infection has been treated.
