Why do people crave sex?

Dr. Michael Roizen, MD
Internal Medicine

Sexual thoughts, for example, go through a man's brain every 52 seconds, and through a woman's only once a day. Perhaps that's because men have 2.5 times the amount of brain space devoted to sexual drive than women do (or because women have more important things to think about?). The craving for sex originates in a part of the left brain called the insula. This primitive area of the brain is especially active in women who have more frequent orgasms.
