Erectile dysfunction is when a man can't get or keep an erection long enough for a good sexual performance. Because ED can be caused by many different physical, mental, or social issues, penis size is not usually linked to it.
Some men worry about their penis size, which can make them feel bad about themselves and less confident. It's important to know, though, that the size of the penis doesn't directly affect how well you can get or keep an erection. Erectile dysfunction (ED) can happen to men of any penis size, and having a smaller-than-average penis does not always make someone more likely to have ED.
Still, worrying about the size of your penis can lead to mental health problems like performance anxiety, which can then affect your ability to get and keep an erection. Men who think too much about their penis size may feel stressed and worried during sexual action, which can make it hard to get or keep an erection. In these situations, talking about the underlying mental issues in therapy or counseling might help boost sexual confidence and function.
