I have a hard lump on the outside skin of my genitals. It is very red and sore and looks like a huge pimple without a head. I have had this before (years ago on my breasts) and sometimes it does come to a head and puss and oil can be forced out with a slight squeeze. I do shave around that area as I am quite hairy and I sweat quite a bit so it feels better to keep the hair short, but obviously shaving wouldn't have caused the lumps on my breast skin. This happens not too often, less than monthly, but it is very sore. Could it just be from my excessive sweating or is it something more serious?
Thanks
