zensturbation 

The act of exciting oneself to orgasm by mental stimulation alone, without any actual physical stimulation whatsoever; thinking oneself into an orgasm.

I've known a few women who claimed to be capable of zensturbation, but I've never met a man who could do it.

an obsession with pens, particularly fountain pens , with obligatory demonstration of your pens,

and writing nonsense on the piece of paper, to show off pen performance.

I committed another act of pensturbation, after spending half of my monthly income to 5 new expensive pens

Zenmasturbation is MUCH more satisfying than just wankin' it.
