really confused

hi, I`ve had oral sex about 3 weeks ago(but i have been very active sexually before that but always protected) and woke up the next day with about 4 medium sized pimple looking like dots on the inside of the skin convering my penis(on top) and another 5 where the skin is attached but those where smaller. I was not worried at first but now they are still present but a lot less visible...I didn`t consult a doctor because i had no symptoms : no burning, no itching, no nothing.I`ve looked up pretty much every single site about herpes and found maybe one picture out of like 30 that could look like what i have. I havent had any discharges either but i have noticed a strange smell. And another thing, i dont think you can pop them.I found this site and thought it was great i would really appreciate someones opinion on this
