What makes people sexually attracted to each other

There may be some biological basis to opposites attracting, too. When it comes to reproduction, a bit of variety works in your favour. For instance, the major histocompatibility complex MHC is a part of the immune system that helps cells recognise foreign molecules.

When the MHC is vastly different from your mate's, this decreases the danger of mating with someone you're related to, and increases the genetic variability of any offspring you have — meaning they're more likely to be healthier with a better immune system.

As people mature, they tend to learn more about themselves. This can work in your favour when looking for a partner, because you're more likely to know what you want and what's important to you. People transfer about 80 million bacteria when they kiss each other , and yet they keep doing it.

Not only does kissing stimulate the release of oxytocin, but the taste of another person also helps with biological attraction. When it comes to heterosexual relationships, several studies have pointed to health being a deciding factor in what people find attractive.

It's not necessarily about body shape and size — although low BMI is sometimes a reason, based on distorted social norms. Generally, if someone looks healthy — they sleep enough, exercise, and eat well — this will probably show on the outside.

And not just in the way they look, but in the way they behave, too. There are certain facial characteristics that are proven to be attractive much of the time. Sometimes it's facial symmetry, but other times it's a crooked smile or unique beauty spot that makes someone stand out.

Averageness and simple faces are often considered most attractive, possibly because standard faces represent a more diverse set of genes.

On the other hand, familiar faces tend to be most attractive, because people may be influenced more by their personal experiences in life than anything else. Similarly the financial success of the top and bottom 25 companies in the Fortune can be correlated to the dominant masculinizing facial features of the CEO.

Like it or not, both sexes have a visceral reaction to these fertile traits. But beauty is not by itself what attracts us. There is something much more vibrant, meaningful and effective that brings people together whether it is for romantic, social or professional needs. Beauty and attraction are very distinct entities. While beauty is raw, primitive attraction is dynamic and advanced. And beauty is just one parcel of what makes a person attractive.

From hair to smell to posture, expression, voice and more—attractiveness is a composite that goes way beyond the surface. By fully understanding the vast and complex array of influences which are packed into those milliseconds we have to make a first impression, we are able to master its outcome. The sexiest person in the room is not necessarily the one who is objectively the most symmetrical or physically perfect.
