I'll have to take your word on that, then. But if you enjoy them, that's the important thing, isn't it? Who cares if you're a guy who enjoys stories about elves; Tolkien was a guy who wrote about elves. Larry Elmore has painted and drawn many dozens of pictures of elves over the years.
You've got a lot of company, so just sit back and have fun.
If you're concerned that it may be considered more of a juvenile form of fantasy... my advice still stands. I still read and re-read one of the mystery series I got into when I was 10. One of the books I'm currently reading is Henry Reed, Inc.; it's a kids' book about a precocious 13-year-old boy who decides to make some money during his summer holidays and gets into all kinds of bizarre situations. One of my bookshelves is filled with Archie comics. Yes, I read those.
So relax. Sit back. Enjoy.
