Help Ladies

I went and got tested for stis and it came back negative. But I have had some itching around my vagina the part right below my belly and my inner thighs. The itching isn’t on going but occurs frequently. I have in the pass spray perfume on my inner thighs and just started using this Caress Fine Fragence Body wash. Could this be an allergic irritation reaction to the wash and what should I use to rid the itching and break out?
