It's not a sin to be attracted to another person A. As you say its perfectly natural and it happens throughout the living world. I know what you mean about the spiritual side of things though.
Jesus does say to love our enemies but it doesnt mean that we cannot love our friends much more and there are a million ways to be attracted to a person: not just the way they look - that's just surface stuff.

hey if you wanted to talk I set up a hushmail account
