Can someboy explain what a receding hairline looks like?

[jonnykino]

... I really don't know what I'm looking for.

I've been on this forum for a while due to me being paranoid about my hair; specifically the crown. I've been told my hair is fine.

However, the past couple of days I've been kinda curious about my hairline. You see, it's not straight. I don't think there's a problem with my hairline, I think I'm a Norwood One... but I don't know what I'm looking for to check for recession. Where does it start? I know what I receded hairline looks like, I just don't know what a RECEDING hairline looks like.

I've got some pics of my hairline;



Straight on, my hairline looks straight. Pulled back it doesn't.

What am I looking for, and what is my hairline?

THANKS, AND SORRY FOR ASKING
