Painting Saint Catherine touches the genital of Jesus with her hand

The depiction you are referring to may not be a widely recognized or traditional portrayal in Christian art. Saint Catherine of Alexandria is typically featured in art scenes emphasizing her wisdom, her martyrdom, or her role as a saint, often depicted with symbols such as a wheel (referencing her torture) or a book (representing her scholarly nature). If you're looking for an artwork that involves a more intimate or controversial interaction between Saint Catherine and Jesus, it could be a modern interpretation or an artist's imaginative representation. Such representations would not follow traditional Christian iconography and might be intended to provoke thought or convey a particular message. If you have a specific artwork in mind, please provide more details, and I would be glad to help with additional information!
