Dire Bare
Legend
Let me first state that I think it would be nice if mini companies made some more various character models. I really do agree with OP.
However, I occasionally sell painted miniatures on ebay and other places. The miniatures that get me the most money for an auction for my effort painting are more scantily clad females. The dreaded chainmail bikini fighters and sorceresses dressed in gauzy fabric.
The difference for me is really noticeable - a regular character figure I paint usually tops out around $45-$55; same painter, same effort for a scantily clad female character miniature $75-$85.
Now, the bonus for me is that I do not have or use many scantily clad females - so selling them is a little easier (I've grown to hate selling my painted models).
But, if I want to make a little extra cash and paint to sell you can understand why I choose those figures.
I do think demand plays a role.
I don't think anyone is arguing that androgynous or gender neutral minis have an equal demand from consumers. "Straight" minis will likely always have a stronger demand, and "sexy" minis will also. But the idea pushed by some in this thread is that gender neutral minis have little to no demand, and I think that is false and says more about our prejudices than actual reality.
