The small dimples formed in the lower back in men and women are called dimples of Venus. They are located in the area where two bones connect the pelvis, and can be seen only in people who have this genetic predisposition, or appropriate size ligaments.
They are a sign of good circulation and a healthy body; a sign of beauty, alluding to the origin of their name, Venus, the Roman goddess of beauty.
Apparently, people who are bestowed with dimples of Venus find it relatively easy to achieve an orgasm! Why? Because the dimples facilitate good circulation, and because of their strategic location around the pelvic area, climaxing becomes easier.
Since they located in an area where there is no muscle, it is impossible to get these dimples with exercise. However, eliminating some fat can make them a little more visible.
