A man sees a woman he’s attracted to. Conversely, a woman sees a man she’s smitten with. Deep inside their brains their hypothalamus glands releases gonadotrophin-releasing hormone (GNRH). This (procreative/sexual) hormone is immediately sent to their pituitary glands to release the gonadotrophins. The pituitary responds by sending the gonadotrophins to the gonads; testicles for the man and ovaries for the woman. This is the scientific way of explaining the ‘big head, little head’ connection which makes the sexual response mechanism possible; it’s another one of our procreative genes.
As a result of this hypothalamus-pituitary-gonadal * responce, a man’s genital region experiences an influx of blood with a corresponding dilation of penile tissue to create an erection. Conversely, the female genital region also receives a surge in blood supply which triggers heightened sensitivity and enlargement of her clitoris, with corresponding secretions of vaginal fluids and dilation of the vaginal chamber in preparation for intercourse.
Needless to say, this is the beginning of new life; our procreative mechanism in its infancy. The brain really is the largest sex organ in the body.
* Often referred to as the acronyms HPGA or HPTA; ’T’ for testicular
