I am a male and had protected sex (condom) with a woman 7 days ago. Yesterday, I noticed that the tip of my penis felt very cold throughout the day, and at night 3 discolored spots appeared on the tip. The spots are pale, skin colored, and only slightly raised (like a mini plateau). They do not look like pimples or bumps, but they definitely look irregular when inspected closely. They also do not hurt, however, the tip of my penis still has that cold sensation today. Is this an early stage of genital herpes and will these turn into blisters?
