2. 5 reasons why girls like to bite boys
1. Express intimacy and possessiveness
Psychological research shows that slight biting behavior is a "love language." Emotions are conveyed through skin contact, while "exclusive rights" are subconsciously marked, similar to the possessive instinct in the animal kingdom.
2. Release pleasant emotions
When a person feels extremely happy, the brain will secrete excessive endorphins, which may trigger "cute aggression" - balancing emotions through mild aggressive behavior, which is common in couple interactions and mother-infant relationships.
3. Establishment of tactile memory
Scientific research shows that human skin has a profound memory of minor pain. Leaving temporary marks through biting is actually a biological instinct to strengthen emotional connections. This phenomenon is particularly common among women aged 18-25.
4. Advanced form of coquettish behavior
In sexual interactions, biting is often accompanied by other coquettish behaviors. Data shows that 76% of cases occur when girls feel ignored or need attention, and it becomes a form of non-verbal communication.
5. Hormones and evolutionary explanations
Biological studies have found that women are more likely to engage in biting behavior before and after ovulation, which may be related to changes in estrogen levels. From an evolutionary perspective, this is also a way to test a partner's ability to withstand stress.

Through analysis, it can be seen that the behavior of girls biting boys is the result of multiple factors, and is essentially a special way of expressing emotions.
