Collage and photo fetishes involve sexual arousal from creating or viewing collages, particularly of body parts or specific themes. This exists primarily in digital contexts.
For some, it's about the visual combination and aesthetics of arranging images. For others, it's about collecting images of specific attributes (feet, hands, eyes, etc.). Many incorporate it into artist expression.
The fetish exists somewhat in gray territory - it doesn't involve another person's participation (typically using public images), but raises questions about consent depending on image sources.
Safety considerations include respecting intellectual property, ensuring images are legally obtained, and being thoughtful about what content is created or shared.
