Yeah, i shave my head too. Same reason. I look awesome.
Fact is, on the average, women prefer men with a full head of hair. Balding men tend to be viewed as weaker, shorter, less masculine. But don't let what women think dictate what you do. Any woman worth having will love you regardless of your hair.
Though i think, as a personal opinion, shaving your head if you're losing your hair can help you retain some of those traits. Some people just have the right shaped head to shave and it looks good. Others, not so much. If you find you feel you look awkward try buzzing it short instead of a full shave, or try growing a goatee or some type of facial hair, etc. Sometimes it may take some experimenting to find what make it look good to you. I think the facial hair helps with retaining some of those masculine traits as well. Shaving your head and a goatee or beard can make you go from baldy to bad boy haha.
