hey man do what FEELS good to you. Like you, I still have enough hair on top that I can let it grow if I want to. SOOooo, I have it both ways - I keep it razor shaved fromm Fall through Spring when I am living in SE Florida. I think it's great! I love the feeling of being clean and smooth. Also I am out in the sun constantlly and trying to put sunscreen on my scalp when there is ay hair there is a messy chore. With the shaved head I just spray on some Nutrogena sheer mist and, - done!
When I return to Illinois for the Summer I sometimes let it grow out just enough to get my very military flattop back on- but that is expensive to maintain nd now thar my hair has turned a mousy grey I think it makes me lood old.
So have FUN with your hair and do what makes you feel good. Others will just have to get over themselves.
P.S. I get more notice from both sexes when my head is clean shaven!
