My penis doesn't go rock hard unless i take a herbal tablet. how can i fix this?

Relax: If you get a better erection from a worthless herbal tablet, it's a placebo effect -- not due to the tablet. There are no herbal tablets that improve erectile function. Instead of the tablet, take some deep breaths, relax and enjoy yourself.

Think about this!: Every male is his worst critic. Stop watching yourself performing, and simply enjoy yourself. You can't watch and judge while performing at the same time!
