I've had beards off and on since I've been 16. It's never been a barrier to my success, either professionally or romantically. I had a momentary crisis when my chin (formerly red) turned white, but that passed quickly.
The last time I shaved my face completely clean, several people told me that it didn't suit me, that I didn't look quite like me. So I've grown it back and plan on keeping it. My gallery pics show my current facial hair.
Without getting into any of those complicated (and to my eyes, rather prissy) shaving/sculpting looks (the infamous "chin strap" springs to mind), a full beard requires that you shave both your neck and cheeks if you want to keep it neat. Lately I've been sporting a mustache/goatee thing, neatly trimmed, and use my beard trimmer to leave some scruff on my neck and the rest of my face. Personally, I think it looks pretty hot, and since I get no complaints, that would appear to be the majority opinion as well.
