real men don't put effort into looking good. nature didn't program men to put effort into looking good. it's a woman's job to look pretty/care about her appearance. it's a man's job to protect her/care for family. creative and sensitive guys (female brain) are stylish. real men focus on more important (manly) things. nowadays many men turn into women/sissy boys (metrosexuals) - feminized and unable to protect. shameful.

Guys always worry about looking "girly", lol. I don't agree with the stereotype about gay men being stylish (I mean, some are and some aren't, just like anybody else on the planet), but here's a short guide to help you decode the rest of your question on style:
A well-groomed guy is actually really attractive. A guy who is OVERLY conscious of his appearance just comes off as being too self-involved. A guy who is shaggy indicates that he doesn't care about himself, let alone the people around him. The exception to the rules are (1) when a guy's getting out of a massive repair job, surgery, or some similar activity, where he's just naturally going to look a little shaggy around the edges; (2) when a guy dresses for a major occasion and is atypically well-groomed (weddings, etc.).
Do I want a stylish guy by my side? Of course, but style isn't just about clothing, it's about "swag" -- personality, not Armani.
Bottom line? Be a Manning, not a Brady... It's important to *look* good, but being good (inside out) is better than being stylish.
