Help please. Dermatitis herpetiformis or herpes?

ive been with the same partner for a year and have had paps and std screenings since. we are exclusive. I decided to use a toy but was out of lube so I decided to try olive oil. I put a condom on the toy lubed it up and used it. it didn't quite feel right but I kept going anyways. now I have hemorhoids and then these bumps started forming. they are painful itchy if I touch them. im so embarrassed. ivery been negative for hsv2

any updates? it could be herpes. get blood tested and swabbed to be sure
