Joh I don't see any mayor unbalance between male and female wearing a CB. Count how many members are male and female with belt we have.
The interesting question would be how many "forced" or "convinced" wearers we have compared by wearers who truly want/love to wear it, splitted by gender.
I am not sure, but I have the feeling that more man wear it because they want it and more girls have to wear it because someone else wants it.
