i am a sexually active 19 year old. i have recently noticed little redish bumps on my penis shaft. they do not petrude much though so i am doughting they are warts. they are painless but they are not going away. this has been going on for about 2 1/2 weeks now and the last time i had sex was about a month and a half ago. I am worried it might be hpv but i am not sure. i dont know what to do becuase i don't want anyone to find out, not even my parents. what would i even say when i made a doctors appoitment?
