Hair down there…

So, I’m 21 and I’ve always had this question but it feels embarrassing to ask… I know everyone has pubic hair, but, is the pubic hair supposed to be on the lips down there? (idk what else to call them) Is it supposed to go all the way down? Or should I see a gynecologist? I’m like super insecure about ever sleeping with someone because what if it’s not normal and they get grossed out? I don’t even like it so why would a guy? So, is it normal for hair to be on the lips and go all the way to the b-hole?
