ANDY'S ANSWERS: OK, I don't know what gave you the idea to shave your pubic hair, but it's completely unnecessary and I certainly would not recommend it.
Shaving can cause you to have in-grown hairs, possible cuts and razor burn, which can lead to pimples and infections, not to mention the incredible itching when the hairs grow back.
It makes me want to scratch just thinking about it.
As far as making your hairs grow higher, I doubt that the shaving has anything to do with that. I would guess that your body hair is just naturally developing as a result of you going through puberty and will continue to do so getting thicker and coarser until you're finally an adult - whether you shave or not.
