OK first off, Nair only works on legs, but good thinking there. Second off, if you don't want waxing to hurt as much, trim the hairs first, then wax. It's not pulling out as much hair so it'll be like nothing's even happening at all. Pull them out one by one instead, waxing is only painful because it's doing that all at once.
Really though I think you should first tell your boyfriend so like you get him the scissors and he snip snip outta the way essentially scissoring it out for ya, two bushes together work better than one. If you're really hairy and the scissors aren't enough, you can just borrow my chainsaw!
Should you want to remove the hair for good, scratch a lot. Scratch so much that you carve your skin open, and then keep scratching. Eventually, you'll scratch all your hair out, and it won't even be growing back. Problem: solved!
