Do I have hard flaccid?

Recently I've noticed that my penis leans/rotates to the left when semi-erect and straigthens out when fully-erect. When flaccid, I can wriggle and bend it etc.

What i'm asking essentially is, what is one thing that 100% determines if I have HF? I've no idea if mine is normal or what. What are the main things to check for to know if HF or not?
