Hi, I am 27 year old. I have had PROTECTED sex six months back. Two months after the sex, I saw a pinkish painless bump at the base of penis. It grew further. But I ignored. Later on, some more small bumps appeared and now their number and size are increasing. Earlier, I had not any kind of pimple/bumps ever. What could it be. How to treat it. I came to know later that the girl had physical relation with some others also.
