Hello. I don't know if this might help or if what you have is similar to what I have had but I recently noticed some dark red "dots", one on the head of my penis and the other on the foreskin, plus some others that weren't as noticeable. Since I hadn't had sex except the boring kind recently, I thought it was odd. So I went to the doctor, explained it to him, had him examine it, and while he said it was nothing, and nothing to be concerned about, he did say that I should wash it with manzanilla, which I think is camomille in english. It's a tea which apparently is great for a number of different ailments. So for the past week of so, I've made this tea, let it cool down, and then I've soaked my dick in it for about 5 minutes at a time (I put it in a glass that is almost full of the tea). And the spots have gone, just like he said they would.
Now I know this sounds maybe too odd but since it's worked for me I thought maybe it might work for you, too. There seem not to be any side effects.
Best wishes.
