I would never let someone read one of my first drafts. Usually I get the structure more or less right in the first draft, but on a line-to-line basis, the writing is ugly and would probably be very distracting. Unless I can dramatically improve the quality of my first drafts, I wouldn't show them to anyone, though I might bounce ideas off people, including my husband. He's never read anything I've written, but I do talk to him about my writing.
