if you're just gonna trim it it shouldn't itch at all. if you're gonna shave it then yeah..it does itch like crazy. try a product called bikini zone. it's a cream found at the druggists and it helps with the itching and tiny bumps you can get after shaving. as to the other question, i have heard (on the dicovery health channel, no less ) that it is only a myth that shaved hair grows in thicker. i'd have to agreee because i've been shaving certain body parts for the better part of 20 years and i've never noticed a difference. as i get older the hair actually gets thinner and grows in more slowly.
