Scientists have revealed the key secrets of sexual desire. They believe there are several reasons why we desire sexual contact with another person.
First and foremost, people are driven by the instinct to procreate . But it's important to understand that the object is suitable for this.
Neuroscientists claim that when choosing a sexual partner, people pay attention to body and facial symmetry . This factor is considered one of the indicators of health and good genetic makeup. A person's temperament and certain illnesses can often be determined by their face. People also choose a sexual partner based on their scent , which they should find pleasing.
Another important factor is the chemical composition of saliva . Kissing can be used to determine compatibility. A couple's brain determines how closely their partner's immune system matches their own. Differences in immunity increase the likelihood of healthy and disease-resistant offspring.
