I have a white pimple like bump on my penis shaft for almost 5months already at first it was only was then it became 3 but the other 2 was gone after a while. But the first one is still there and its been 5months. After that i noticed on the shaft of my penis where my pubic hair is came a few bump that look different. Im getting worried if they are std since ive had unprotected sex when my gf has period when this started.
