You might be having this tight foreskin called prepuce since childhood. If the aperture in the foreskin hasnt grown with age then at times it needs a surgical correction. Some have foreskin which goes more than 50% of the way and hence they can be helped with lubricants and foreskin loosening manually.
Next Steps
Kindly consult a surgeon and get examined. They may advice a circumcision which is a simple operation done for various reasons. some do it for religious reason, some do it for problems like yours, while there are some who do it purely for cosmetic reason. A circumcised penis doesnt offer great help to the individual;except it is easier to clean it. But a person who can roll back his forskin can also clean it well. So dont be afraid. It is just a day procedure and you may be discharged after few hours to 24 hours depending on your surgeon
