Kama Soul

The body is full of hidden erotic zones that can match the pleasure capabilities of the breasts and genitals. Discovering them is one of the true joys of sex. Couples who fully explore and understand these areas are on their  way to becoming expert lover.
perineum 
This small, nerve-rich area is located between the anus and the genitals in both men and women. Explore with your finger, your tongue, or a sex toy. The prostate in men and the perineal sponge in women (found underneath the perineum) are also highly sensitive. When these little areas are stimulated, the results can be quite pleasurable—even orgasmic.
A-spot
Also known as the AFE spot, this female hot spot is a relatively new discovery. It is located between the G-spot and the cervix, at the very end of the vaginal canal on the anterior wall. This is also known as the perineal sponge, which can be stimulated during anal sex. When aroused, this area can lead to intense orgasms, along with plenty of vaginal lubrication (in fact, the area was discovered by sex researcher Dr. Chua Chee Ann, who was looking for a way to treat women with painful vaginal dryness). 
P-spot 
The P-spot is a male hot spot named for the prostate gland. It is a small bump located just inside the anus, which can lead to deep orgasms when stimulated. Be prepared for fireworks when playing with this erogenous zone—it’s known as the male G-spot for a reason
U-spot 
Another female hot spot, the U-spot’s name comes from its location just above and around the urethral opening. Some women also release ejaculate from the urethral tube during orgasm. This is completely normal, and can be a thrilling sexual experience for both partners. Women also find stimulation  to the area around the U-spot, called the peri-urethral region, very arousing due to the many nerve endings located there.
