2. *Prolactin surge*: This hormone helps regulate sexual satisfaction and can lead to feelings of relaxation and sleepiness.
3. *Dopamine drop*: After the sexual high, dopamine levels decrease, which can lead to feelings of sadness or melancholy (known as "post-coital blues".
4. *Increased intimacy*: Sex can strengthen emotional bonds and increase feelings of closeness.
5. *Improved sleep*: Sex can help regulate sleep patterns and improve overall sleep quality.
6. *Pain relief*: Sex can help alleviate pain, including menstrual cramps and headaches.
7. *Immune system boost*: Sex can increase antibody production, helping to fight off infections.
