STD?!?

Hey y’all, okay so I’ve been sexual active with this dude and everytime we have sex we use condoms. They itch sometimes everytime we use them but this time ( which was a couple of weeks ago) my private swell, had bumps on my labia and was red. It was really irritating! And I think it spread to my butt and I had this huge rash on my neck. A couple of days later the rash went away, and my itch down there died down but I ended up getting a yeast infection (I think). I don’t know what do you guys think? Has anyone had an allergic reaction to condoms or spermicide? Or do you think it’s an STD? ( I know you guys aren’t doctors, I’m just a girl trying to see if anyone else went through the same. Basically just looking for same experiences!)

The bumps don’t look like blisters, and when I touch them they don’t hurt at all. I can use the ladies room just fine ( meaning I don’t burn when I go to the restroom) and I can sit down comfortably. And they don’t have puss in them. I also don’t have a quirky smell. Hopefully it’s not an STD.

Back story on me and him: we never have raw sex EVER! IM in a monogamous sexual relationship with him. ( meaning Hes the only boy I have sex with!) And I can’t say for sure if he’s in one with me! I also went to the doctor and she said it just looked like irritation and it wasn’t herpes but she didn’t test me and I’m still worried. I haven’t done anything with anyone since because it’s on my mind. What do you guys think?

- Thanks!
