If your sun sign is Gemini, you were born between May 21st and June 20th*
Gemini's quick wits and silver tongue can really charm your pants off, and if you were born under this sign, potential lovers probably fascinate you. Your single-minded interest in your lovers will make them feel special, and your experimental fire is likely to lead to passion and excitement in the bedroom. Solo sex, BDSM, role-play and romance are all on the cards for imaginative and powerful Gemini, who often possesses a talent for performance. Take care with that whip, however, because natives of this sign can be quick to bruise. It is true that these fiery folk can struggle, at times, from a fear of commitment, but there is also the sense that Gemini (whose symbol is "the twins") is always looking for her/his/hir ideal partner, and lovers who are strong enough to express intense emotion can certainly inspire a Gemini's love.
In terms of physicality, Gemini is all about the arms, hands and lungs, so do take advantage of those dextrous fingers, which are wonderful in both solo and partnered sex. As for erogenous zones, kissing, massaging or suckling on Gemini's fingers or arms is likely to build them into a lather. And if you're sleeping with a Gemini, you might note how beautiful those fingers look when pressed against your skin...
Enjoy your twins, Gemini! And remember...your astrological chart is a mix of all sorts of aspects (including your Moon sign and your Rising sign, to name but a couple). So if you are a Gemini and any of the above doesn't sound like you, then it probably isn't! This is a just a generalization.
