You're fine, Dear. I don't think there is ever anything 'normal' about a fetish. And, that is why they should be embraced (unless dangerous of course!)
You can look at another girl without being homosexual. It's a sort of admiration. Don't worry about it.
As for your man. xD Ask away! Fetishes are something to be shared between partners. A man WANTS to turn on his girl, let him know just how to do it! Of course, he may ask you to assist in the indulgance of his own fetish but that's one of the fun things about relationships.
Personally, I have a pretty odd fetish in my opinion: Formal wear. Give me man or woman, in a suit and tie combo and I can barely stop myself. xD I also have an uncanny love of human anatomy, so even a body in it's prime is exciting to me. I also love x-rays, but there is no way to implament this into the bedroom and I don't I would want to try.
