Your Sex Sign is...

You've got a ton of girls and guys trying to get with you! You're pratically booked up for the next four years. Not only are you great in bed - you're great at making people feel sexy. No wonder you're so popular! Libra, as you probably have noticed, you are always surrounded by scores of admiring suitors. You are a very accomplished flirt. Catching you is not for the faint hearted. Competition is always fierce. Your innate charm and incredible looks instantly attract - and keep - your lovers. Old flames and rejected suitors always keep coming back for more. There is a strong bisexual element in your personality. You're more likely to be aroused by the same sex than other signs. In threesomes, you are more likely to prefer that one partner is opposite sex and that the third is same sex. Your lovers adore you because you are a real ego stroker. You are eager to please and will do almost anything they ask. You are a born diplomat, which comes in handy with all of your suitors. You always win fights too, because your charm is irresistable!
