Body hair has to be one of the most natural things ever.
A while ago (before I got a boyfriend), I used to think the exact same, so what I'm going to tell you, comes from someone who's been in your situation:
Your body is beautiful, because it's a part of YOU. Every line, every scar, every spot, every hair.
You are a virgin, and if you are nervous about your first time (because of hair), I advise you to do this: don't have sex. Make love with a person you love (cheesy, I know), and who loves you back. It makes things far easier, and if a person loves you, they most certainly won't be bothered by hair. They fell in love with YOU, not hair, or the absence of it.
If you choose to do it with someone you don't have a particularly romantic relationship with, or a relationship at all, it still won't matter to them. If it does, well, it means that they do not deserve having the privilege of being your first time.
If you already have a person in mind, how about talking about the hair first? It might give you a preview of their reaction (stay away from immature guys!).
If you do not feel comfortable in shaving/waxing it all off (like me), don't.
It's your body, not anyone else's. You do what you feel okay and safe in doing.
If you want to keep it controlled, instead of shaving, you could carefully cut it with round scissors. It's what I do, hihi.
I'll leave you with lyrics by Tim Minchin:
"This is my body
And I live in it
It's 31
And 6 months old
It's changed a lot since it was new
It's done stuff it wasn't built to do
I often try to fill it up with wine
And the weirdest thing about it is
I spend so much time hating it
But it never says a bad word about me"
Be calm, and trust me: feel comfortable with yourself and your partner, and everything will be alright!
