Masturbation over the years does not usually cause any permanent change in penis tightness, and this concern is often related to anxiety. Feeling stressed can affect confidence and sexual performance. Focus on a healthy routine, regular exercise, and stress control to improve overall well-being. Avoid overthinking or guilt related to this habit. Consult a doctor if the concern continues or causes distress.

Difficulty maintaining an erection can happen due to many reasons, and it is more common than most people think. Stress, anxiety about performance, poor sleep, relationship tension, excessive masturbation or pornography in some cases, smoking, alcohol, lack of exercise, diabetes, high blood pressure, obesity, and hormonal imbalance can all affect erection quality. Sometimes the problem is mainly psychological, especially if erections are normal during sleep or early morning but not during intercourse. Improving overall health often helps a lot; regular exercise, good sleep, reducing stress, quitting tobacco, limiting alcohol, and maintaining good blood sugar control can improve blood flow and confidence over time. Avoid constantly testing erections, as that can increase anxiety and worsen the cycle. If the problem has been continuing regularly for several months, or if there is reduced sexual desire, fatigue, or other health issues, it is important to get evaluated because conditions like diabetes, low testosterone, or circulation problems may need proper treatment.
