IWhat do you think it is?
I noticed it right after shaving
Could be herpes or irritation from shaving. Did you notice these before you shaved or after?
I would recommend you get an HSV IGG test to see if you are infected or have been infected with herpes in the past. Remember, you must test 12-16 weeks after your last encounter to really feel somewhat confident in the results.
If I were you, I would also see a dermatologist to get their opinion and get those bumps swabbed for herpes just in case.
