Masturbation can have both psychological and neurological effects on the brain. When an individual masturbates, the brain releases various neurotransmitters, including dopamine, which contribute to feelings of pleasure and satisfaction. Regular masturbation can help reduce stress and improve mood due to the release of these neurotransmitters. Additionally, it can promote better sleep and relaxation. However, excessive masturbation might lead to feelings of guilt, anxiety, or addiction-like behaviors, which can negatively impact mental well-being.
