Is it in fact necessary to urinate after sex? The reason why I ask is because after my partner and I have intercourse, I rarely feel the need to urinate. Additionally, I don’t understand the connection between urination and sexual intercourse, what does urination after sex accomplish?


To answer your question it is good idea to empty your bladder before and after sexual intercourse because it is one way to prevent urinary tract infections (UTI). UTI’s are usually caused by a bacteria called E. coli which travel from your colon to the urethra and bladder. Since these three areas of your body are in close vicinity to one another, sexual intercourse facilitates the E. coli to be transferred from the rectal area up into the urethra. Once the bacteria is situated in the urethra it multiplies, thus causing a UTI. Naturally, however any sexual activity that irritates the urethra puts pressure on the bladder, making you want to urinate. If you are having problems urinating, try drinking more water and other fluids. In order to prevent irritation to the urethra, try to avoid prolonged direct clitoral stimulation and make sure your vagina is lubricated. Rear entry positions and prolonged vigorous intercourse tends to put additional stress on your urethra. Emptying out your bladder before having sex flushes existing E. coli out of your urethra. Urinating after sex prevents E. coli from settling into your which may ultimately cause a UTI.
