Herpes Doctor

About two days ago from today I had some irritation down below. I thought it was from shaving too close. Now I don’t know what to think. It kind of burns when I urinate and I have two bumps that look like pimples on one lip and one kind of by the hole. I never really get yeast infections (think I had maybe 2 in my life) or urinary track infections (not sure if I ever had one) Now today the rest of my vagina has tiny little bumps from the hairs growing back but kind of hurts. Could it be the razor I used? I've been with this guy for 4 months and have never noticed anything on his penis. It has been really hot and humid the past couple of days can that have anything to do with it? What do I do?!?!?! Oh also after having intercourse I usual don't go to the bathroom right away maybe like 2-3 hrs later usually or once recently overnight (happens about 2x's a week) Another thing is I have has intercourse during my period 2-3 times in the past 2 months for the first time.... Someone please give advice ASAP
