I've been told as a kid that having a crush on someone is completely normal and should not be deemed weird or out of this world. You can have as many crushes as you like, my Mom said.
To be honest, I've never been vocal about my crushes, unless they were animated characters or people from the telly who I may never even meet IRL. I'm also quite vocal about my crushes over at social media.. well, unless it's not awkward and stuff. What am I even saying? Jayvee, you're such a dork.
