I had circumcision about 2 yrs ago. During the operation a tiny area of the glans got nicked/scratched, and had a blood scar as typical of scratches. It healed and now that area looks nearly normal blending with the rest of the glans but if you closely look and feel the area, you can subtlely notice the scar (visually & texturally - slightly different texture from the glans but mostly smooth).
Anyhow, was just wondering how common in general does such a thing happen compared to other operational problems like issues with the stitching or the cut.
