My best advice would be go and get waxed, the more you shave the thicker the hairs grow back. If you get waxed the hair gets thinner every time and doesn't grow back as much and as quick.
It's relatively cheap and if you take a pain killer before you go then it doesn't hurt at all
Just don't get tempted to shave inbetween waxing or you will ruin your hard work!
Don't get worried about going and showing your bits either, they've seen it all before!!!
Hope this helps.
