How do you keep it smooth? NSFW

So I’ve decided I want to be smooth and stay smooth in the nether regions, but I’m not sure what’s the best way to keep it up. It grows back after about a day or two and it’s super painful if I try to shave it when it’s that short. I usually just get in the shower and use a disposable 2 blade. Also, if I’m constantly shaving, how can I avoid the itchiness and pain when it’s spiky and stabby?
