I think Coyote makes some very good points, although I will admit that I do try not to make fun of men. I'm devoutly het, despite a penchant for writing slash, and on the whole I quite enjoy men. I'm also willing to laugh at myself just as quickly, and try not to treat one gender as superior.
But on the whole, I think any intelligent reader wants a little character development, unless you're just in one of those PWP moods. Otherwise, it's like being a little kid again, and vowing that when you grow up, you'll have dessert for dinner every night. After a while, it starts to get boring, and frankly unappealing.
And I stand by my assertion that fruit should not be used to describe a woman's anatomy.
