Advice on what to do!

I’ve got some red bumps that I get from itchy skin down there.. not IN my vagina but on the outside where the pubic hairs are. It goes away oddly enough during my period. But when it comes back it’s like comparing it to mosquito bites and I start to itch until the skin is raw & red. I’ve been using vagasil & it’s worked wonders. Any other hygiene products I should use?
