See URO: You are young at 21 to have an ed issue, and the medications will work, but sometimes can cause a "dependence" reaction on the medications. Several ed issues can be related to performance anxiety or "stress issues." other causes could be high blood pressure, diabetes, etc, so best to see a urologist to get properly tested before falling back on the medications. Good luck!
