I do believe that straight shaving has, so far, claimed the lives of many many sorts of facial hair. I can tell you for myself... I never really got to grow the mustache I wanted because the "call" of shaving it off is always too strong. My girlfriend is always happy to see the mustache disapear, though...
I've read several times here that many beards have been reduced to goatees and many goatees reduced to mustaches and many mustaches reduced to... nothing. You're not alone in wanting to shave more and more. It is just such a pleasurable experience.
