###Human: I am unable to pull my penis foreskin back. Why and how to correct it? ###Assistant: Hi. Your problem is known as phimosis. In this, the penis foreskin cannot be retracted back. For that, a topical steroid can be taken. But mostly, most of the patients need an operation called circumcision. In that operation, the foreskin is removed, and a tight frenulum is released. It is a minor daycare surgery. I suggest you consult a urologist for circumcision.
