I've just recently discovered that i have what look like pimples on my penis and they are very very sensitive to the touch. i popped one already but another one grew back and its very thick and white. i know my girlfriend was previously diagnosed with chlamydia but she was treated and its gone now. ive heard that these could be ingrown hairs and when i popped it before, i plucked the hair out, but im too scared to pop them again because it hurts to even touch it. i dont want to have sex again until i know exactly what it is. i cant go see a doctor because i have no medical insurance so i really dont know what my options are. i am really scared, i dont know if its an STD or something not even serious. PLEASE HELP ME!!! what could this be?
