Huh. It's come down to tastes at this point; penis, for me, is far hotter than cock, and it doesn't feel like the writer is avoiding actually confronting what they're dealing with. I sometimes think that smut writers get as abstract, flowery or just plain crude to save themselves from the embarrassment of writing sex. I like a writer that doesn't hide behind that sort of language.

I find myself unable to separate the word 'cock' from the image of a rooster, or (sexually speaking) a dark sex scene, akin to rape. I have no idea why the sexual connotation is that way for me - it just is.

Hahahaha, oh yeah. Context might be important, here. *hits self*
