Help me

hello so i recently have been experiencing some weird sympotoms and idk how to go about it so like a week ago i had unprotected sex and while in the middle of it my partner grabbed my butt and spread it apart to far and caused me to rip my butt crack at first i just thought it would heal on its own and it has but in the last day i was experiencing these bumps on my butt and they are kind of itchy in not sure if its because its healing or what has anyone else experienced this or no? ive been trying to be research but ive been scaring myself and im to embarrassed to go to the doctor and im scared its herpes

nothing to b embarrassed about if u can post on here u can see a doctor they see things like this day in day out looking at the spots they dont look like herpes but could b other things its best to have them looked at
