It is possible for some men to experience physical arousal, including getting an erection, when they are angry or experiencing strong emotions. This response is often due to the physiological connection between emotional and sexual arousal in the body. Anger can trigger the release of adrenaline and other stress hormones, which can increase blood flow throughout the body, including to the genital area, leading to an erection.
However, it's important to note that the relationship between anger and sexual arousal is complex and can vary from person to person. Not all men will experience this physical response when they are angry, and not all erections are solely related to sexual arousal.
If you or someone you know is experiencing difficulties with anger or other emotional responses, it may be helpful to seek guidance from a mental health professional or counselor to explore and understand these emotions better. They can provide valuable insights and coping strategies to manage emotions effectively.
