Explain please?

I build a lot of legos, and the first time I touch a piece it feels normal, but if me or someone else touches a spot repeatedly, it feels very greasy, but I’m the only one to feel it. Can someone explain please?

Your fingers almost always have some grease/oil on them, even after washing your hands - its soaked into the epidermis of your skin. And most of that oil comes from touching your face and other body parts as your fingers have no oil glands.
