Thank you, Hezzie!
One thing I discovered about nail polish is that it works just like the paint on my car. I mean - I work in heavy construction, I have to wear steel-toe boots all day. They have no ventilation at all, so they trap moisture and breed nastiness. I've always, forever, been terribly embarrassed to let anybody see my feet. But the paint hides the fugliness, and it protects my toenails from the dampness and decay. That pink - "girly" as pink is - was 1000x better than my natural feet, and I was not embarrassed at all to be seen wearing it. Then, the extra exposure to light and air healed my feet completely, and (my theory..) residual solvents help prevent reinfection. By the end of the first week, I couldn't wait to change the pink for a better color, and my toes have been polished ever since!
Ladies, I'm serious - there is no real reason for guys to avoid a "masculine" color on their toes... and there's actually a good reason for men TO wear nail color. If your man has foot/shoe problems like I did... PLEASE encourage him to let you paint his toes! OPI's "Roadhouse Blues", BB Couture's "Grenade", ManGlaze's "Matte is Murder" (black, matches a Glock 9, google "Scrangie Glock" to see a photo..) or "Santorum" (reddish espresso matte brown - you'll like it on you with a gloss topcoat..) are all excellent choices for men. Take one week to try it, then see how you both feel about it.
Hezzie, here's a blue I wore - "Blue My Mind" by OPI.
