Should maaaaaybe have limited voting to the females, as male bias is going go make your results all screwy when it comes to finding out "what the ladies dig". And yes, there have been men voting in your poll, lots of them.
This is a bad place to pose such a question anyway, because you have a very limited audience of grrrrrrlz, and an overwhelming male audience is definately going to give you some form of beard-bias.
And Also, I shave. Clean shaven all the time, a tiny bit of chin-stubble if I get lazy.
Captcha: ecifro regularly. Whatever ecifro-ing is, be sure to make it a part of your daily routine.
