The dong, the shlong, the anaconda, the baby-maker — whatever you wanna call it, the penis is a very special part of the body deserving of attention.

In this stream, sex educator Reba Corrine, aka Reba the Diva, gives us the lowdown on how to maximize penis pleasure.

To give and receive the best penis pleasure, it’s important to first understand penis anatomy. The head of the penis, or the glans, is covered with nerve-endings, making it ultra-sensitive. The head of an uncircumcised penis is even more sensitive as the average penile foreskin has 20,000 nerve-endings. The pee hole, or the meatus, also can be sensitive, but often gets ignored during sexual activity. The head of the penis is separated by the shaft with a ridge called the corona, and the underside of the shaft, where the head meets the shaft in ‘V” shape, is called the frenulum.

Since the frenulum is particularly sensitive, Corinne suggests trying “the flicker,” where you flick your tongue up and down, left or right, on this part of the penis. Travelling down the shaft of the penis, you’ll notice the penile raphe, a vein that separates the two columns of spongy tissue in the penis that fill with blood to produce an erection. Corinne says the upper part of the shaft responds best to friction, while the lower parts respond best to pressure. That’s why putting a cock ring on the base of the penis can help strengthen and prolong erections.

The scrotum, or the balls, holds the testicles. Corinne suggests treating this area like very delicate eggs and caressing them slowly and gently. Some people like their balls touched while others don’t, so it’s important to communicate with your partner. Since the penile raphe vein goes all the way down to the balls, you can try tracing it with your tongue from the head to balls.

To stimulate the prostate, a chestnut-sized organ inside the body, you can apply external pressure to the perineum. You can also stimulate the prostate through the anus with fingers or toy, and curving up toward the belly button. Prostate stimulation can lead to a P-orgasm, which some report to be a more full-bodied orgasm.

Understanding penis parts can help you give and receive the most pleasure. Just remember to always communicate with a partner throughout any sexual activity and to be vocal about what does and doesn’t feel good for you.
