Over the weekend I had sex with a woman for the first time. the next day I noticed there were about 5-6 very small, almost pinpoint like red dots under my penis head and a couple on the base of my penis head. They have not spread or worsened in condition and I guess it is possible that I got them right after sex but I did not examine myself. Just wondering what this could be. I've heard broken blood vessels and yeast infection. Dots are not raised just looks like a discoloration. Help is appreciated thanks.
