DrSkipper, I hope to find more time soon to share my thoughts on this, but I'll keep it short for now, since I'm way past the time I should have been asleep.

You're normal. It's perfectly normal to have fantasies about other people. Ideally, you'd have fantasies about your boyfriend, too, but sexuality is a complicated thing and I don't think it means you don't like or care about him. I find it hard to fantasize about real people (except celebrities, but they're still kind of fantasy personalities), but I don't think there's anything wrong with me. Hugs to you!
