Shaving without pain?

So, yes...I remember a time when I was wild and free...my bush trimmed, but certainly not absent. I started shaving my bikini line in high school...but the real shaving didn't begin until I met my husband. He has been "clean shaven" for years (way before I got a hold of him)...smooth balls are nice against your chin...and no wayward hairs to get stuck between teeth or at the back of the throat (ee-gads, I hate that). So, he made the fair request that I, too, go bare.

The first time I shaved...I broke out in a rash almost immediately. But, I had liked the feeling of being hairless so much, that I knew I was going to have a to find a way to at least keep it somewhat maintained. I tried a Brazilian wax once (maybe twice, I can't remember). It was so horrendously painful (and yes, I've had children and been tattooed several times, so I know what pain is and can usually get through it). I just couldn't face it again.

So, I found myself a couple of decent tools (the to keep myself trimmed up without much "after burn") . But I still have to go a few weeks between shaves. I can't do it daily or weekly, because I still tend to rash up. I wish I had a better system, and I have researched it extensively, but none of the tips seem to work to keep the razor burn at bay. I've experimented with different shave creams, water temp, shaving while submerged in water, after lotions, creams to help control in-grown hairs....none of it works.  It isn't the shaving that's the problem...it's the maintenance afterward. 

Anyone have any great ideas...something I may not have thought of trying?
