Watching natural-looking people engaging in sex that is consensual, pleasurable and realistic may not be harmful--heck, it might be a good idea--but that is generally not what the billion global porn industry is shilling.

Its producers have one goal: to get men off hard and fast for profit. In a study of behaviors in popular porn, nearly 90% of 304 random scenes contained physical aggression toward women, who nearly always responded neutrally or with pleasure.

Studies have found that the longer and deeper a man has slept, the higher his testosterone levels.

Although you might have different versions of eye color on either one and that determines what you display. Research suggests, however, that in a few births per thousand some individuals will be born with a single sex chromosome (45X or 45Y) (sex monosomies) and some with three or more sex chromosomes (47XXX, 47XYY or 47XXY, etc.) (sex polysomies).Clearly, there are not only females who are XX and males who are XY, but rather, there is a range of chromosome complements, hormone balances, and phenotypic variations that determine sex. Similarly some females are also born 46XY due to mutations in the Y chromosome. In addition, some males are born 46XX due to the translocation of a tiny section of the sex determining region of the Y chromosome.Women also make testosterone -the main sex drive hormone -but produce a fraction of the amount and it rises by only a tiny bit overnight.
