I have what I would call a pimple at the base of my penis right above my scrotum that fills with a whitish liquid, same as any acne, and has been around for at least 3 months. I think an std or sti is unlikely considering I ve had no contact with anyone but myself including sex or any body part. I would like to know what it is.
Good Day, and thank you for being with Chat Doctor !  It might be an acne or a blocked sebaceous gland. these things are benign and are not cancer, but I would ask you to see a doctor to be sure. If it bothers you can always get surgery, and it is usually an outpatient one.  Manuel C. See IV, M.D. DBU FPGA
