I'm only 17 years old but I've been feeling maternal hormones lately. Every now and then, when I see a guy that I like, I'd mentally make babies with that guy. Now what this means is that I'll ponder over the boy's looks and then try to mix them with mine to see if I can mentally imagine our kids. Then I'd proceed to think, "We'd make cute children" or whatever. I thought it was just a harmless game to play with the people I have crushes on, but some of my friends think that it's weird. My question is do YOU think it's normal?
