Why am I only approached by older men? I'm 15?

I'm fifteen almost 16. Only older men approach me randomly when I'm out in public. Youngest has been 22 and oldest has been around 45. They still talk to me (say it doesn't matter) even when I tell them my age. Why do older men do this? And why don't many guys my age approach me?

I don't look older than my age at all. I've been told I have a baby face actually. But what I'm wondering is why in general older men hit on younger girls?
