You said your doctor prescribed
Cialis. All three PDE-5 inhibitors (Viagra,
Cialis,
Levitra) are very effective but everyone
is different and reactions vary greatly. I suggest you try all three and see which one works best for you. You should always consult your doctor first, though. Have you seen a urologist already? Did you do any tests to determine if there's some underlying organic cause that you're not aware of? Maybe you should seek a second opinion. Good luck!
