Love who you want to love
No you're not stupid. You are normal. Girls love a guy bigger than they are. First no girl wants to be bigger than her MAN. Second women love feeling safe and protected by their MAN. That's why they are men... it's their role in society to "protect" and "care" for their woman. It's one of those things that no matter how equal society becomes that won't change. Men are strong women are soft. That's why we attract each other. Keep doing what you are doing. Even if it were "weird" it shouldn't matter. You shouldn't change what makes you happy. You can't help who you love, right?
