nope I think a lot of people start looking at themselves in the mirror. I probably started looking at myself in the mirror around age 11.
How old are you?

completely normal. And it also depends on how much or little you know to expect, what parents may have said, what u may have seen with older siblings or cosines if u have any, seeing friends in changing rooms,
if you have any questions on anything, here is as good as place as any to ask

It's all normal to look at ones self in a mirror, I don't look everyday as you can't tell too much has happened in a day but I look every other month or so and notice more pubes , belly fat and size

Not weird at all. Using a mirror is a good way to see how your body is changing

in our spare bedroom we have a full length mirror that I like looking at myself in periodically. It’s interesting when you look down at your dick it looks small but when you look at yourself in the mirror it does not look nearly as small. I’m sure girls do the same thing looking at their breasts.
I don’t even think it really has anything to do with puberty because I’ve looked at myself naked in the mirror when I was probably 9 or 10 years old

I mean I look at myself I'm the mirror to get ready for school to see my clothes and hair. Nothing wrong with looking in the mirror while naked as well. First time I ever heard about toes growing I must say lol. But I mean everything is growing on me, I guess toes are too. Just never noticed.

Staring naked in the mirror is not something out of the ordinary and you are not the only one who is doing it. When i was10 or 11 i started looking too to see the new "changes"
