One reason that older men are more likely to experience impotence is the fact that they are likely to have more physical problems and be on medications. Many medicines can cause impotence. There are many causes of impotence. Some of these causes are physical, psychological, or a combination of both. Others may include the use of alcohol, especially when used in combination with tobacco, which increases the likelihood of impotence, diabetes, prostate problems, heart disease, and others.
Alcohol often increases sexual desire while decreasing the ability to function.
If you have sexual problems soon after starting a new medication, you should suspect the medicine and contact your healthcare provider. Consult your healthcare provider before changing the dose or stopping your prescribed medication. Psychological causes may be less likely to cause impotence if you have always felt comfortable with your sexual performance. While it may take longer to get an erection, older men are usually able to maintain an erection. If you are like most men, as you get older, you will need more direct physical stimulation to get an erection.
