#1 You're curvy
Biologically speaking, a curvy woman, especially if those curves include big hips, tend to be really open-minded in bed. A study out of the University of Leeds has found that women with large hips are more prone to one-night stands and casual NSA hookups and are more open to experimenting sexually. The thought here is that those hips go hand-in-hand with the procreation, so when it comes to sex, curvy ladies rule the school.
#2 You're short
I once had a guy friend tell me he loved sleeping with short girls because their compactness allowed them to do things that taller women can’t and it’s easier to have sex in more places. As a shorty myself, I tend to agree. But from a scientific perspective, shorter women also have a lower center of gravity meaning they have hella awesome balance making tricky positions as simple as pie.
#3 You're tall
Although a study found that both men and women with long legs are, on the surface, perceived as sexy and healthy, once they get into bed it’s not always fireworks. This isn’t to suggest that their technique is bad but tall women don’t have the opportunity to be tossed around in bed or can easily have a quickie in a public place. This can be a bit of a hassle, especially if the woman is taller than the person she’s banging.
#4 You're chubby
According to Nobel prize-winning geneticist, James Watson, women who are chubby are more likely to enjoy sex than thin women. As the man who discovered the structure of DNA, he firmly believes that from a biological standpoint the more fluff a woman has, the better her personality and the better she’ll be in bed. Why? Because all that fat boosts endorphins which increase sexual desire and prowess, making fat girls killer in the sack.
#5 You’re skinny
Unlike their chubby counterparts, skinny people do not have a boost in endorphins; therefore based on geneticist, James Watson they’re not so great in bed. However, another study found that men perform best when they’re in bed with a woman who has a thin waist, so that’s something.
