Sex on the Male Brain

            I have always wondered about a lot of things in life. Majority of those things I have found out the answers to as I got older. Such things as why rainbows appear in the sky after it rains. I learned the answer to that question in high school physics. The simple answer to that was the light from the sun is reflected and refracted off of water droplets in the air and is separated into the different colors of ROY G BIV. .
             Even though I've learned the answers to almost all of my wonderments, I kind of still wonder why does the average male always have sex on his mind. As a female when I was younger I always thought of it as them being horny all the time, or as our parents would say their hormones are raging. I personally would really like to know why they have "sex on the brains" at least thirty seconds out of every minute. .
             I know and have learned that hormones have a major role in the male brain and sexual behavior. Such hormones/androgens as testosterone and estrogen which are produced by males and females play a significant part in male sexual behavior. Being that the brain is also a sex organ, both of these hormones are regulated by the brain. Estrogen is produced in a small amount in the male which is important for maintaining mating in males. In simpler terms it keeps the male wanting the opposite sex. Testosterone is produced in large amounts in the male for a number of reasons. Reasons such as helping the male sex drive going in a healthy manner. During puberty, testosterone is required for the development of male secondary sexual characteristics, stimulation of sexual behavior and function, and initiation of sperm production. In adult males, testosterone maintains muscle mass and strength, fat distribution, bone mass, erythropoiesis, male hair pattern, libido and potency, and spermatogenesis.
             I've also learned that the male brain responds greatly to sexual stimuli. Researchers from the INSERM research unit 292, specialized in public health, Paris, did a test on five men being monitored by a positron emission tomography.
