NEED ADVICE!! Keep getting rashes on my vagina

Faith

I have been getting bumps and rashes on the top of my vagina (where the skin is, not the lips). Some of the bumps have puss in it which I have to sometimes pop and blood usually comes out with the pus. These bumps usually hurt and sometimes get really big.

Am I shaving wrong ? I don't know what to do please help !!! It keeps occurring and I'm very uncomfortable with the sight !!!
