That is a pretty severe skin bridge. Skin bridges are a common complication of infant circumcision. The skin bridge forms where the skin adheres to the glans. Doctors are supposed to tell parents to watch for adhesions when their baby is circumcised, but . . .
The adhesion in that pic will most likely require a surgeon to correct. Here is a link to one man's story:
Overcoming a botched circumcision (skin bridge). If that was my penis, i would have it fixed. I would call a plastic surgeon so that any further damage would be minimized.
