Maybe it's the anus's main function that makes you think twice about rummaging around back there. And like the female g-spot, prostate massage-literally being rubbed-has been known to induce a more prolific projection of ejaculate. For men, the prostate is a highly sensitive erogenous zone that can provide similarly intense orgasms. You've heard of the g-spot right? It's the name often given to the spongy area on the inside front wall of a woman's vagina that is said to produce powerful orgasms. It's located below the bladder, and is sometimes known as 'the male g-spot.' That spasm you feel when you ejaculate? That's the prostate hard at work. The rest is largely sperm and seminal vesicle fluid and these ingredients mix during orgasm. What this walnut-to-plum-sized gland does is secrete a slightly alkaline goo that makes up around a third of a man's semen. If you're a man or have one in your life, take a moment to put your finger on what the prostate is, how prostate massage is done, what it feels like, and why you should or shouldn't be afraid to try it.
