There are shaving creams that help to make it easier to shave down there. There is this stuff called Coochy that helps a lot, you can't get it at a store, it's a Pure Romance product. But if you go to the store you can just look through the different things and some of them will say that they help for making shaving easier and whatever.
Have girls never thought about using a guys beard trimmer? You can get a decent beard trimmer with all kinds of attachments for cutting at different lenghts and even trimming very close for about $20. I know this because I bought a beard trimmer for that purpose, I have to shave my face every day so I never have a beard. I don't shave my pubic region but I like to trim it down short so I'm not a bush man. Seems like this contraption would help you ladies out in the long run!
I use Nair . I know I know they say not to use it but it really works.
I have this problem too. Trim it first. Trim it as close to your skin as you cann without cutting yourself. Make sure you do this in the shower becausr it's messy. That makes the hairs thinner and shorter, which makes it easier to shave. Then use a razor and shave perpendicular to the way the hairs are growing. That way it won;t itch. Hope this helped :)
