Pap smear?

🪐 E.T 🪐

What age are you suppose to go and get a Pap smear. I've wrote a post similar to this before but got all different answers. I'm 16 and I'm sexually active (if that matters) and I've never been educated on Pap smears, what they're for, how they're done etc and would just like some information from anyone who knows.
