You could also try switching to a new razor blade every time/every other time you want to shave. I tend to get razor burn on my shins more than any where else and I've had luck with using an acne body scrub and rubbing alcohol afterwards the day before I plan on shaving.

I did get a Brazilian wax right before my wedding. I ended up with horrible bumps, but then tried triple antibiotic ointment (Neosporan) about 3 times a day and it cleared it up almost immediately. I didn't find the waxing too painful, and when it grew back it wasn't nearly as irritated or itchy. I'd love to do it again... maybe when finances allow or when I need a super good reward for myself.
