Hi I am 19 years old, about 5.7ft height and 75kg weight. I noticed recently that i have what looks like a scar behind my testicles on both sides where my inner thigh connects. They are on both sides and look like the skin was stretched or something and healed and the skin is thinner now. Btw I noticed it while showering so as I was poking around with it. I accidentally pulled the 'stretch mark' and the darker lines on the mark started to bleed. (It looks like a stretch mark, length is like 3-4 inches and 1 inch width ) Anybody know what this could be?
