Don't know if this is herpes or not

Long story short I had unprotected sex a few days ago. Afterwards I shaved so I don’t know if this is from irritation or herpes. The area has felt tender and sore for about 2 days with noticeable redness. I do see hairs in some places with bumps but in other areas where there are bumps I don’t see any hairs. And there was a bump about 1mm or less big that had a white head and a tiny amount of pus.
