Mercury is the closest planet to Sun. It revolves round the Sun faster than other planets. One of its sides constantly faces the Sun and therefore has very high temperatures, whereas the other side never faces the Sun and has temperatures below zero. These extremes of hot and cold temperatures perfectly display the changing and dual sexual behavior of those born under the sign of Gemini.
Among negative Gemini types one may find an experimenter, a satyr (among men), a nymphomaniac (among women), an exhibitionist, a fetishist, a homosexual and a pervert. The positive types are: a celibate, a selfless artist, an athlete, a scientist, a man of high morality. In general, their passions are so directly linked with thinking that it is the moods and interests that stimulate sexual relationship. Here we find a non-conformist, who once denied all conventions of the society, joined a group of hippies and lived their community and afterwards denied this bohemian lifestyle. If the astrologers were allowed to give a different symbol to this sign, they would choose a chameleon, which changes the color of its skin as a disguise.
A free and easy Gemini will try all ways of making love, at least once. Nothing is too shocking for him. Since Mercury rules writing, the Gemini often have a secret diary where they keep a score of their sexual partners with all their merits and demerits.
The Geminis are not really aggressive and easily accept the second place in all spheres including sex.
