What is the ruling on penis enlargement using daily massage and oils, and what is your advice regarding that?

Enlarging the penis surgically is forbidden unless there is a medical necessity (if it is very short and affects intercourse). As for natural methods like creams and manual exercises, there appears to be no religious impediment, provided that it does not result in harm and that touching the penis with the right hand is avoided. This is not considered forbidden masturbation unless it is driven by lust and intended ejaculation. It is worth noting that it has not been scientifically proven that penis length affects marital intercourse. It is more important to focus on good marital relations and cultivating affection.
