Hairy body parts...please help.?

It's a bit embarring but here goes. When I was 13, I noticed that my was quite hairy, so I tried shaving it....and after a while, it grew into a forest. The shaving doesn't even last me long so I want an alternative to it. Also, I started shaving my inner thighs for some reason and now I grow really long, black hairs. I found my rectum was hairy too and did the same. I look horrible and I feel so self-conscious. What should I do? I wouldn't mind waxing but I'd be so embarred.
