How do i regain strength in my erections?

ED: If you are having problems with poor erections at 18 y/o, you should be examined by a physician to determine in the problem is organic or psychogenic.

Look for cause first: To assess if one's erections have weakened, he should visit a primary doctor, who can check for possible causes: stress, depression, diabetes, high blood pressure, low testosterone, artery disease, high cholesterol, etc... Causes found can be treated to help make erections stronger, firmer, longer lasting. A urologist can be helpful. Meds like viagra, cialis, levitra, (vardenafil) staxyn, or stendra can work.
