I can't find a hot guy face anywhere--I've looked pretty extensively. Maybe I'm the only straight guy who wants to look good in this game, but eh. Are there any suggestions?

Personally, I love adding celebrity faces into the game. Each companion I have, I give them a unique face.
You can create face texture files for Oblivion using FaceGen Modeller.
Of course, you'll need to know how to add them in CS, too.
The other option is to download Race mods that come with good looking face textures.
I think the recent Moonshadow Elves look really good. You should check that one out =)
