Only with a custom character, afaik. When you make a custom character, you get 300 characters to make a description. You can also describe yourself to NPC's,, and they'll generally remember it, if you emphasize for them to do so. I constantly had to remind NPC's I was a quadrupedal creature that walked on four legs and after a while, they didn't need reminding anymore.
Though, I now realize that could just be a Celandine-ism. Celandine is a slut and will flatter and flirt with just about any character that talks to her in my experience, even with no prompting at all.
