Seeing changes in your husband's sexual performance is one way to tell if he has Erectile Dysfunction (ED). If you have trouble getting or keeping an erection during sexual activity, this could be a sign of ED. Watch how he reacts, because he might feel frustrated, embarrassed, or avoid situations because of the condition. Communication is very important. Talking about any worries or changes in closeness in an open way can help people understand. If your husband complains about his sexual function or avoids all personal situations, that could be a sign that you need to see a professional. You should encourage him to see a doctor because ED can be caused by many things, such as underlying mental or physical health problems. When talking about possible ED in an open and helpful way, both mental and physical health are protected.
