Enhancing silicone dolls - massage oil and fragrance

I’ve heard numerous times that it’s bad to touch oil to a silicone doll because it will harm the paint. If someone wants to simulate a massage session (with massage “oil”), is there a better option that just using a water-based lubricant and pretending? That seems really messy and sticky.

Same problem with fragrance - they’re nearly all oil-based. I bet it would really help bring the illusion to life if the doll smelled a little more like a person would smell (like a person who wears perfume or uses scented body lotion).
