Pimples or STD?

a couple months ago i noticed small pimples which i thought were ingrown hair. but recently one started growing larger.

no pain, itch, or discharge. the middle one is the biggest one and its getting harder as it grows larger. when it started it was probably 2/3 of the current size.

the small red spot is accidental cut while shaving. so they are not normally open sores.

are these just normal skin health related stuff or should i go get tested?

i recently got tested but not blood test, i came back clean.

What you could try is to get a Liquid Antiseptic that is used to treat cuts, grazes and insect bites on the skin.
Check the instructions on how to use - I would apply initially 3 or 4 times daily. It may really sting the first couple of times you apply it. Use the antiseptic for 5 to 6 days, if it worsens at any time, or it simply fails to clear after 6 or 7 days you need to seek medical attention, as, if you have already had these for 7 or 8 weeks already you need to have them correctly identified and treated
