narla's right... pubic hair can be successfully waxed to maintain hair length. Or the hairs can be shaved... mine seem to grow back exactly same way it was prior to shaving... neither softer; nor coarser. I recommend an electric shaver that has a comb on it if you chose to go that way. You can also trim the pubs to a manageable length. Just use a regular hair comb as a guide and carefully clip the hairs with scissors.
I have my pubic area waxed,it grows back very soft and if you get it done regularly,about once a month it doesn't hurt.I will admit the first time really hurts.

Also, different people have different sorts of pubic hair (just as they have different sorts of head hair). Some people just have thicker, rougher, or coarser pubes than others, and there's not much you can do to change that (other than trimming or removal).
