My penis was circumcised when I was little but a small part of my glans are attached to my penis.
Can it be removed through an operation?
How much will it cost?
Are there any side effects and does anyone know what its called?
It sounds like a skin bridge (see link). You should see a doctor as to how it can be rectified.

I would hope that your glans is attached to your penis. If it’s not you have some serious problems.
