Crasterbation 

Crasterbation is when you masturbate too much and then you have to decide about coming later as you've been spanking the monkey too frequently.

I was crasterbating this morning and had no problem getting a woody but since I crasterbate everyday of the year I understand why I wasn't able to cum. To crasterbation is to pull the pud.

Casturbation

Casturbation relates to the art of masturbating whilst wearing a cast (caused from broken bones somewhere between the individuals wrists and shoulders).
It can often require a lot of patience and training depending on the size and location of the cast.

Dan: Must be hard for you, being single for the last 7 months and not even able to choke the chicken with that broken wrist?
Jeff: It was rough for the first month, but casturbation is really my only option
