Is it normal that the foreskin of my penis doesn't retracts??

It doesn't retract on it's own, or it doesn't retract at all? Not all foreskins will automatically retract on their own. This is normal and nothing to worry about. However, if your foreskin does not retract at all, you should probably get it checked by your doctor. It could be fused to the glans from not washing under it, or it could be phimosis. If it is phimosis, your doctor will treat it by giving you stretching exercises, cream, or in some cases surgery.

maybe you need to take a shower and clean it

If it won't retract at all, that's an actual medical condition and you might need to see a doctor.

Steroid creme, circimsision or bloody ripped foreskin by sex. You choose.
