Real doctors won't give you a prescription for erection pills to you especially if you're only 25, without trying to diagnose what your problem is. Not being able to get an erection means you have a health problem of some sort. If the doctor can fix the health problem, whatever it may be, then you don't need erection pills. Also, they won't give you erection pills if you're not healthy enough to begin with. And if you're already using other medication for something else, they probably won't give it to you. No sane doctor will just hand over erection pills without asking questions or finding out more about your health.
