I reckon if you are a good-looking man and your appearence is important to you, then there is no harm in enhancing it with available products.
If however like me you were not sprayed with evolution's cologne, then you make the best of what you have, and 99% of said products would be wasted.
I bathe regularly, I shave when I feel like it, I have my Number One done once a week, i clean my teeth properly, I always smell nice - deoderant and cologne every single day, and I always carry a clean handkerchief.
That's doing the best with what is - for the rest, I rely on my wit and conversation, which are streets ahead of most of the rest of my gender.
(Oh, and I loathe false modesty as well!)
