Some couples always seem more hot and heavy than others, don't they?

Like they are going at it whenever they have half a chance. And guess what? Now you can too – you just need to make sure you pick a partner born in the right month of the calendar year, that's all.

Yup, that's true. Apparently, when you are born has a huge impact on what you are like in the bedroom, according to astrologer Suzie Kerr Wright, who explained to Cosmopolitan what your birthday says about your sex life:

January: Those born in January have 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. They have a lot of passion, but you have to really work for it. Their heads are focused in causes and the bigger picture, but you really have to try to get them to connect emotionally. It's not that you can't connect emotionally, but you better be prepared to work for it.

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 and often take sex to new heights of spirituality.

April: April-born people are very independent, so when they're involved with someone, they give their all. Sex with an April-born person is hot, intense, and very passionate because they're ruled by Mars. Their passion is huge, but they often get tired of people quickly.

May: May-born people want sex to be comfortable and sensual and warm. They love the act of sex itself. They want to make love on satin sheets in a gorgeously decorated room or not at all.

June: June-born people will want to try every position under the sun because they want to know everything about everything. They're not as intense as February-born people, but they're still intense. 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. They love to nurture people and make sure they're satisfied and have everything they need.

August: August-born people can either be extremely selfish or extremely generous. They'll want to make sure their partner has everything. 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 when it comes to sex, it'll take a lot to really get them to let go and have a great orgasm. They won't immediately throw themselves into sex, but if they have an emotional component there, there's nothing they won't do.

October: They want to paint a romantic, passionate picture, and tell you how it'll be and how you'll feel. Then once they tell you, they want to go very slow and make the experience last. They'll really take their time and linger and romance someone. 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 are the epitome of what passionate sex is. They need to possess their partners and want their partners to possess them and will make that happen. They will try every sex act imaginable just to say they've done it.

December: December-born people are very creative in bed. They love to create stories and role-play with partners. It's often hard to connect to them in a deeper way, but they'll make sex fun every single time.
