I don't render males a lot, but what I'm usually missing are skin textures for more rugged men.  Also for men who are in their 40's.  It's hard making a render of a man in his very sexy middle years when all of the character textures are for 20-something pretty boys.  The skin is just different.

Hair.  Again, too many pretty hairstyles.  Too much pomp and poof, and not enough rugged or every day.

Clothes.  So much is effeminate or something an average man wouldn't wear.  I want jeans that look comfortable and average, not skin tight and up to his rib cage.  I'd love more clothes that are good for post-apocalyptic wasteland images and biker gear like the guys wear on Sons of Anarchy, but that's just me.
