Hey there,
I'm a 17 year old male, and for about a year and a half now, I've had a long, scar-like mark that extended from the base of my genitals and into my inner thigh. It was very similiar to a scar, as the skin there was much thinner. However, it has small, evenly spaced lines which run horizontal to the mark. I'm not sure if these are veins or what, though.
Anyway, the mark has gotten considerabelly longer, and is now 3 inches. The tip of it is dark red. I think it's because I've been itching it, although I haven't been conscious of that until just tonight. There's also another small mark which has appeared a bit below it, although this one is only about as long as my pinky fingernail.
Here's an image of the larger one, although the quality is very poor:

Anyway, does anyone have any clue of what this could be? I wasn't too worried about it until it started itching, and another one appeared.
