If you’ve got a penis you may have heard about your prostate. It’s kind of important. Well lucky for you, giving your prostate a massage during sex can increase sensation and basically feel real nice when you come. The Agency for Healthcare Research and Quality writes,
“The prostate gland is the size of a walnut. It is found in front of the rectum and just below the bladder, which stores urine. The prostate makes some of the milky fluid (semen) that carries sperm. The prostate wraps around a tube (the urethra) that carries urine from the bladder out through the tip of the penis.
During a man’s orgasm (sexual climax), muscles squeeze the prostate’s fluid into the urethra. Sperm, which are made in the testicles, also go into the urethra during orgasm. The milky fluid carries the sperm through the penis during orgasm.”
Just like how women have a g-spot, that if stimulated can make them ejaculate a clear fluid when they orgasm, men have their p-spot that has the same function, but most men can ejaculate without the prostate stimulation.
