How are you down there?

Hey ;) 
I got a question :) 
Do you shave down there or wax ... Or something like that? I am 16 and I want to shave ... But it kind of hurts... I get these little red not pimples bus something like that if  I shave myself.... But u don't know if I can wax myself down there by myself ... And does it really hurt that bad? 
Another question if you shave can you get all the hair away!? It doesn't work for me... But I don't really know what to do... I'd you have any ideas I am glad to hear them ...
( sorry for my English  i am from Germany)
