Weird white spots/bumps

last sexual contact i had with someone was over 6 months ago and she has no symptoms or std to her knowledge of any sort, these just started apearing here a few weeks ago they arnt itchy it does not burn when i pee and i shower on the regualr i dont know if its new flordyce spots or the start of hpv. last time i went to my dermotologist they were almost certian it was nothing, i just asked for them to have a look since i go there for my egzema and was told not to worry tottally normal i just wanted a second opinion you know? just to ease my mind or before i decide to go to a clinic for a screening ive also havent noiticed any discharge or weird colored cum. just realised it is very hard to pick up on camera very pale white spots

So yes, you did the right thing getting the Dermatologist to check - and being told " was told not to worry tottally normal " does not seem to have put your mind at ease.
If you want to be a 100% sure go to a Sexual Health STI Clinic for a different opinion …
