Shaving tips???? Please help!!

E
I prefer to be hairless "down there" not because I'm having sex or feel like I need to, It just feels nicer and cleaner to me. But I always get bumps when the hair is growing back and I don't have time to shave every day. I hate that it gets so itchy and irritated, are there any tips to get rid of those itchy bumps or prevent them from showing up?
