main causes of erectile dysfunction during intercourse are the physical, psychological or lifestyle factors. It is recommended to seek the advice of a specialist in sexual health including urologists or sex therapists, so you can talk about your concerns and find out the real problem. They can offer you the right treatment plan and improve your sexual performance.

To begin with, over-masturbation does not bring about anxiety. Social anxiety you have can make you feel anxious when interacting with people in various environments. Signs include thoughts that won't get out of the head and head pain. Tension or genetics can be the factors. You could give deep breathing practices a shot or get some counseling. Always keep in mind that these emotions are usual and that they can be managed with encouragement and different techniques.

Don’t worry too much about it though because many people do masturbate; however, if one does so excessively this could be the cause behind what you’re going through. You might start feeling weaker than usual or notice some changes like less energy in general - all signs pointing towards too much self-pleasure being unhealthy behavior. So, try mending your ways by eating proper meals and working out often since these two acts will help accelerate recovery from this condition should they have already set in.

Itching is a common symptom of infection or irritation after a week and a half of masturbation. Gently clean the area, avoid using strong soaps and wear loose clothes. If it continues, stop masturbating for a while and check if there is any difference. If there is none, seek medical attention.

This could be due to various reasons like anxiety, stress, or even certain medical conditions. It's a must to have thorough communication with your partner and be as relaxed as possible during intercourse. Try out these techniques too; the start-stop method and consulting a doctor can be beneficial. 

Being overwhelmed with the consumption of explicit material, and being involved in related behaviors can cause feelings of guilt, anxiety, or distraction from daily activities. This usually happens because of curiosity or stress. For example, limiting screen time and taking up other forms of hobbies such as sports or reading can be incredibly helpful. Creating a supportive circle of friends or family can also be beneficial.
