Taking care of your vagina

Laura • Quiet but chatty once you get to know me!
Hey, I've been shaving my vagina for a few months now and would like tips and advice on how to shave pubic hair on the vagina. I'm unsure of how to shave every pubic hair down there and wonder how I can fix this. And also what about the back (the hole where a guy would insert his dick during sex - I'm guessing ~ don't know much about sex)
