Should guys who are balding just shave it off?
I would.
I'm not bald now, and fortunately I'm not even starting to go bald at the moment. I'm almost 30 though and my father had hair surgery and my grandfather is bald. So it's possible that I might one day and I've thought about what I'd do if/when it happens. Personally, if I start to lose my hair, I'm reaching for the razor.
And I do have a goatee, which I have no plans of getting rid of (maybe ever).
tec - you said:
Bald is sexy. (I came to this conclusion after I found Jean Luc to be one sexy, bald and older man :)
I'm assuming you mean Sir Patrick Stewart (who played Jean Luc Picard on Star Trek: The Next Generation for the non-trekkies). I actually met him once at a Comic Con. You're right, he's a good looking guy. After we got his autograph and spoke with him briefly, my girlfriend leans over and whispers to me "That is one SEXY man!"
