Hey Prog... so, Peniphobia, the fear of big dicks being waved in your face. Why only big dicks? Are small dicks OK?
Cram... I have one similiar to your plane fear. Since my digestive system was seriously re-worked during my cancer surgery things now move a long at a very fast pace. From the time I know I have to go, it could be as little as 3 minutes until disaster. The scenario I worry about most...is when I'm scuba diving. I would have to take of all my gear while underwater..tank, vest, and get my wetsuit down. After that..while still holding on to everything (still need that air source...LOL) I would have to perform what is referred to as "The Warhammer Manuever" If your curious..it's on youtube, or at least it was...LOL.
My BIGGEST fear is being buried alive. Living in earthquake country I fear the house collapsing on me during an earthquake and being stuck for days slowly dying. If Hell is a real place... being buried alive would probably be the worst punishment for me...
