Need help now!!!!!!

Is this herpes?!?! I had sex with a new person friday night, I was drunk and he pressured me.. i woke up feeling fine, but then around 6pm last night (approx 14 hours later) i got these red itchy bumps near the bottom of my butt. I took a shower and the hot water made it worse, it made it feel sore and itchy. It was on both sides but now its only on one. I wanted to believe it was razor burn but I havnt shaved since like Tue or Wed. Now Im starting to think otherwise and im freaking out! The itch and pain comes and goes. They havnt blistered yet but is the beginning of a herpes break out?! Someone please help me!! Ive been crying all day. I will be going to the dr in the morning but just wanted to see if anyone knows what this could be. Thanks so much for all your help.
