Vaginal pain

So I lost my virginity last month and it was fine (meaning no pain) but afterwards I got a yeast infection. I went and got tested for chlamydia and gonorrhea and bother we’re negative and I didn’t think anything of it. I got Monistat and then got my period and I was fine. Now this month I’m on antibiotics (for swollen lymph nodes which I got earlier in the year as well) and I’m on my period right now. But my vagina (or rather my vulva like my labia minoras) hurt to touch. I don’t think they are swollen. But they are painful and I feel dry. It almost looks as though my skin is peeling. I’m not itchy and it doesn’t hurt to pee or anything like that. It’s skin irritation. I don’t have any bumps or blisters or anything that looks like herpes. And the man I was with was clean (supposedly) we had sex twice and used a condom once. I’m going to the OBGYN in January but I just wanted to know if any other women have experienced this or could give me a little insight on what’s going on. By the way I’m only 18 almost 19 but I’ve been doing my research and trying to educate myself the best I can. Thank You
