skin trouble😞

I seriously cannot get any answers. And please don't make fun of me. I am so embarrassed already. So a few weeks ago I had noticed I had a few bug bit looking bumps by my vulva. So, me being a hypochondriac I called my OBGYN and got std testing. Everything came back negative. But I keep having these red itchy bumps showing up around my vulva and on my butt checks as well as this one under my armpit. Does anyone know what this is or has had something similar? Any suggestions on what I should do. I'm super embarrassed to be naked around my boyfriend just because these bumps keep scarring. I used to have flawless skin and now it looks like this.😞 please help.Â
