My family has no history of baldness on either sides. Almost everyone on my dad's side, however, has a widow's peak. I'm not shedding an unusual amount of hair, and my hair is still full and thick. Can someone tell me if this is a receding hairline or just maturing? I've included as many images from now and earlier times as possible for verification.

Second question: I'm new to this website, why won't it let me delete posts? I tried posting this before multiple times but kept messing up; it won't let me delete those posts.
