Aquarius-Gemini Compatibility

A romantic relationship between these two won't be wine and roses. If the Aqauarian has Venus in the Fishy sign of Pisces or the Gemini has Venus in caressing Cancer, their relationship will have a more romantic ring to it, but otherwise they'll both be bright and breezy in the bedroom and when they make love it'll be more like a balmy breath of beautiful air on a magnificent morning then a torrent of thunder and lightning in a summer storm. If they aren't careful,sex can change from cool and carefree caresses to cold and calculating consummation.
