I am so romantically inept

Okay, so, I'm Marcus, a transgender, panromantic boy attending Hogwarts School of Witchcraft and Wizardry. I'm in my fourth year, and I've never been in a relationship. However, I'm hoping that will change soon, as I've recently met a very attractive fifth-year boy in Ravenclaw. The problem is, I have no idea how to make a move...
