Me? Feel bad? Never. Years ago, when I first was introduced to the realm of slash fiction by a dear friend, who would animatedly talk about her love of doujinshi anywhere, I asked her (in the middle of a conversation about gay erotica in the middle of a crowded cafe) if she was never embarrassed about it. She said, "The way I see it, you can either be ashamed or unabashed, and I will never be ashamed!" Wise words!
Other than being sensitive to people's discomfort I'm not embarrassed about anything. I've somehow managed to develop a reputation for brash and/or weirdness which I'm not particularly, and it all stems from liking what I like and not caring whether it's deemed worthy by others.
