Differently shaped temples

[Autumn Sundown]

One of my temples is circular, the other one is square. They both go back to the exact same point (if I trace a line down they come to my cheekbone)
Is this normal or am I losing my hair?
My hair is very, very thick, all the hairs I shed are thick all the way through, no scalp pimples, tenderness or itch.

half of the men on my dad's side are bald, no one on my mom's side is.

My hairline is much lower than most other people' who are around the same age as me (18.) It's just that most people have either square or or round hairlines, I have both.

I couldn't tell you if you are losing your hair or not but i do know a lot of people have uneven temples, a majority of my friends have temples where one side goes back on angle and is more "sharp" where as the other side slopes up slightly. It would be good if you can post pics if not then it doesn't really matter, either way just keep a eye on it.
