Phobia (from the Greek word for "fear") is an unnatural yet very intense fear of a certain element, noun, person, or situation. For example, people who don't like being near, being in, or swimming in water are Aquaphobic. People who don't like being near or seeing fire are Pyrophobic. And people who don't like being in confined spaces are Claustrophobic.
I don't think phobophobophobia is a word.
It isn't a real phobia, but, etymologically speaking, phobophobophobia is the fear of knowing that you have fear. Someone who realizes that he or she has "phobophobophobia" would probably go insane.
Fear of erect Penis (or seeing someone else's.)
Phobaphobia is an urban word which means you're afraid of fear
I would assume its the fear of the penis
Foliphobia is the fear of leaves.
The fear of leaving is called agoraphobia. This progressive phobia is the fear of leaving the house. It is associated with a panic attack.
Im not expert but I believe gradual exposure may help. Depending on how intense your fear is, chart a step by step increase in exposure to leaves to assist in becoming fear and anxiety free. Pick a leaf up with gloves, place it in a plastic wallet, touch it through the plastic, remove it with gloves, touch it against your foot, gradually building up until you can bear to have it touch your face. Start with a small leaf and build upwards.
