Im 13 and i was looking in the mirror....before i took a shower anid i noticed 5 little brown marks or blobs on my booty. Theyre kinda small. I dont know what they are and im worried more will appear. I have one on my hip and i dont care about that one because a guy wouldnt care and its a birthmark. But these marks appeared in april 2014. Can anyone tell me what they are and how to make thm disappear? And they look like a kinda bigger freekle
