Hi, new to the forums(and slightly embarrased for posting here) In my pubic region, the skin is itchy and when I scratch it, the skin over time turns darker and no hair will grow there. This is slowly starting to spread. What should I do? I also have to admit that Im a bit overweight. Could this do anything with it? Also, when I scratch beteen the "v" shape and the leg, sometimes it goes red(especially in the summer) what should I do here?

I forgot to metnion -I am 16 and virgin(if this helps at all)
