Scientists working on the sexual chemistry of the male human have made some surprising discoveries. They have found that a man who starts to feel sexually attractive to a female either his wife or girlfriend or even a slapper in a bar produces a hormone that influences his brain to see all that's beautiful in a woman.
This effect can last from three to five hours or a little as 25 seconds depending on the age and experience of the male.
What the scientists have also found out is another chemical produced after the man ejaculates that make his partner look "a right rough dog" and that is the reason he closes his eyes and falls asleep thinking "I must be pissed"!
