HELP ARE THESE SKIN TAGS

i went to a urologist and he said everything was normal, i am still very worried, they are right in the fold of my foreskin, i am 18 and have never had sex. i used to masturbate alot with no sort of lube. please help! i have also had these for a while and i am prone to skin tags and so is my family

Its not from sex or masturbation, but they are infectious bumps. They seem to be red which means they could be blood spots. Blood spots develop from blood flow and infection.

is that bad? like what type of infection if its not sexually transmitted??
