Herpes on butt???

so lately I’ve been getting what look like pimples on my butt that are itchy, and its been happening since i had last had sex. I did also move to a hotter place then I’m used to. so my question is, does/can herpes look like pimples on butt ? or can it just be something else causing this? if anyone that does get herpes on butt post a pic or describe it. please and thank you.
