Is this herpes I’m SCARED

I noticed this 3 days after intercourse with my boyfriend. There is a slight itching sometime but no pain. Does it look like herpes or another std??

it looks more like its related to shaving but still u should go have a blood test to be sure seen as it appeared after sex

thank you! i just went to the doctor and they said its probably a bacterial skin infection

thanks for the update
