I don't mind writing them, but I do hope the members of my critique group don't see me as the character. I never thought about these things until I experienced writing them. When I read something written in first person, I certainly don't picture the author as the character. And I don't think about it reading other people's work in my critique group. But now that I'm taking a sex scene for the first time to my critique group tonight, I hope I won't be embarrassed when they read it. And no, I'm not the character, but I am in the character's head when I'm writing her.
