Erectile dysfunction in your 30s can happen for several reasons, including stress, anxiety, depression, lack of sleep, smoking, excessive alcohol use, obesity, and poor eating habits. Health conditions such as diabetes, high blood pressure, and hormonal imbalances may also affect erectile function. Relationship issues and performance anxiety can make the problem worse. While ED is often associated with older age, younger men can experience it too. Many men use Cenforce 100 mg to help improve erections by increasing blood flow to the penis. However, identifying and addressing the underlying cause is important for long-term sexual health.
