Shaving

syd • syd/24/ttc baby #1 😭💜
Hello Ladies! I've had some curiosity, I've been shaving, down there, for about 2 years now, like fully shaving it, and I find that when I don't shave for a bit it's gets really irritated and itchy. But when I've shaved it feels fine and there is so itch at all. (Unless there is razor burn which is sometimes but not all the time) 
I'm not talking about where the lips are, not like all up in there you know what I mean? I'm talking about the lil triangle part below your tummy. That's what gets irritated when I haven't shaved, it'll itch, and get red bumps (the bumps go away when I stop scratching ,sorry for the tmi!) Any solutions and does this happen to any one else?
