For a long time I have had these marks on my inside thighs, close to my genitals. These marks are also on my chest and neck. They look like birthmarks, or kind of like a puddle of blood under the skin. They are not irritable, I wouldn't say they are rashes, and the skin is not really dry or unusual. The marks are a sort of orange, light red color. The two by my genitals are darkest, and then the ones on my chest, three, are fainter, and the one on my neck is fainter still. They become faint and almost invisble when I shower too. I can remember them being there as early as 16, and I am 20 now. Is there anyone who has anything similar to this, or any idea what it might be.
