Shaving for sex?

Alrighty guys, so I've never had sex. But I've been thinking a lot about it.  And I'm looking for some advice as I'm feeling a little distressed about the hair situation. 
Its something I've noticed no one really talks about. How do you shave down there? Everyone says guys like a shaved p*ussy, but I'm always scared to shave too close to my vag. Also do you shave your butt? I know these are kinda silly questions and some people have told me to just get it waxxed. But I don't know how that would work. And I don't feel comfortable with someone working down there. 
I also get razor burn and in growns when I do shave. I would greatly appreciate your advice in this as it is one of things holding me back from having sex.
