nvizible, have you considered growing a beard, or keeping some stubble? I don't mean any offense by this, but you have a "weak chin". It's very tapered, somewhat feminine looking, and probably what lead to the lesbian comment earlier. I personally don't like beards, unless you're Rye or Cultpop, but it might be worth a try, at least for shits and giggles. I have only heard about this beards for weak chinned people recently, so don't shoot the messenger.
If you're against growing fuzz, and I'm sure a lot of people here are against facial hair, listen to poly's suggestions... get the back trimmed up a bit. Also, try a bit of product in your hair to keep it from frizzing up. I recently tried to do the longer hair thing, and it just wasn't working - it was either too dry, or too oily, and far too fucking hot in the summer (I sweat like a fat man).
Also, the square rimless glasses aren't the best look for your face IMO. Your face is oval/triangular, and I think you might do better with some frames that have softer edges and are more rounded, less rectangular/oval. I also think rimless looks best on the over-50 gentleman crowd.
