Thanks for your question. It is recommended to gently retract (or pull back) your foreskin when you urinate. You should pull back just far enough to see the meatus (the hole where urine comes from, this is typically at the tip of the penis). This helps to prevent an infection.
We also recommend gently retracting your foreskin when you shower, and cleaning your penis with mild soap and warm water.
If you are not able to retract your foreskin, you should see a healthcare provider.
