Chemistry is a funny thing. Sometimes you have it, something you don't.
And while we may have always thought it was a case of trial and error, it turns out there's another technique that you can use to figure out whether you're compatible with someone in the sack.
According to Cosmopolitan, you can predict exactly what they like to get up to just by figuring out their star sign.
Hmmmm... we can't say that we're entirely convinced but here's their rundown so you can check it out for yourself!
January: One of the kinkiest signs. You wouldn't think so, but they're right up there with November birthdays in terms of being willing to experiment in bed.
February: February-born people are adventurers with a lot of passion, but you have to really work for it and it can be hard to try to get them to connect emotionally.
March: March-born people love spending time in bed. Sex for them is very intense and bonded because they give their partner everything they have.
April: Sex with an April-born person is hot, intense, and very passionate but they often get tired of people quickly.
May: May-born people want sex to be comfortable and sensual and warm.
June: June-born people will want to try every position under the sun because they want to know everything about everything. If you want someone to talk dirty to you, they've got you covered.
July: Sex with July-born people has to have a deep emotional component. They have to feel safe with someone and once they do, they will do anything to please their partner.
August: August-born people can either be extremely selfish or extremely generous. They hate being told what to do in bed, and their egos are easily bruised.
September: They're passionate but they're always in control of their emotions,so they won't immediately throw themselves into sex.
October: They want to paint a romantic, passionate picture, and tell you how it'll be and how you'll feel. October-born people might lack passion, but they make up for that with spot-on courting that leads up to romantic sex.
November: November-born people will try every sex act imaginable just to say they've done it.
December: December-born people are very creative in bed. It's often hard to connect to them in a deeper way, but they'll make sex fun every single time.
