It is true that when we have body odor, we are secreting hormones to attract the opposite sex so maybe the hormones just appeal to you a lot. And there are plenty of guys who like skinny women.= so you aren't alone on that one.
When it comes to those kind of things like who you are attracted to or why you like a certain person, there is no such thing as normal. Everyone has different tastes and people should respect that. So you're fine with just the way you are.
