Is this herpes?!

I’ve been getting open sores on vagina lips I can’t tell what it is, every time I shave down there my vagina will have a little itch then these sores come this is my second time seeing the same exact open cut the first time wasn’t as bad just you can see that it’s pink/whiteish inside of the open cut. The second time, I had 3 little white bumps that looks like pimples I took a hot bath then maybe 2-3 Days it pus out and turned into a sore the sore didn’t scab it just went away on it’s own and then near my vagina hole it was a bump that sort of look like a skin tag I’m not sure how to describe it but it was painful when I walk or sit down. I had sex right after I shaved and I shaved really close to my vagina hole, I also continued to have sex while the 3 little white bumps that looked like pimples were still down there I’m not sure if the Sex is what caused the sore or to think I have caught an std
