banana boner 

A boner that curves upward, resembling an upturned banana. Legend has it it's especially good at stimulating the elusive g-spot on the female anatomy, but I wouldn't know because I have a straight boner.

The banana boner is a mystery! How can a curved biological structure be so rigid?!
