Marc,
You are absolutely right. I overlooked that possibility.
Too short circumcision is a distinct possibility - or too tight foreskin.
Too tight foreskin can often be improved by simply stretching with your fingers after using lots of lubrication. It will take a few months. It can also be improved by what is called a dorsal cut - a timy cut that loosen the foreskin,but does not eliminate it.
A too short circumcision can be imporved my lots of lengthy procedure men do who regret being circumcised. But a doctor can also do a bit of palstic surgery and attach a ring of skin to length en your foreskin.
