I am 18 years old i have white dots on my penis and little penile papules on penis i had protected sex with a girl few months b4. i am scared abt std?

White bumps on Penis: Hi. This is most likely not a std. Without seeing these lesions i would guess that they very easily could be warts. Or, they could be small hair follicle cysts known as sebaceous cysts. Anyway a good men's health expert may be able to identify and treat this for you.

Penile lesions: These lesions would need to be examined, a history obtained & other tests may be necessary in order to diagnose them. Usually the lesions needs to be identified to determine the solution.
