Most Helpful Guy
Beauty or handsomeness is always a positive quality.
However. Beauty or handsomeness is completely subjective. Therefore regardless what the "most common opinion" *possibly* is, that barely ever applies to an actual individual. Thus, some might find you attractive, some might not. Some might think you're pretty, some might not. Some think you're beautiful, some don't.
So being handsome does matter. But it's nothing to be wondering about, 'am I pretty'? Some think you are, some think you aren't. What matters is whether *that specific person* that you like, does HE think that you are attractive. That is what *truly* matters, really.
