Even before knowing how to properly care for my silicone toys, or even starting a toy collection, i always used/preferred water-based lubricants. While silicone lubes will last a little longer and has a wonderfully smooth texture, they can degrade materials and are not suggested for use with some condoms. Oil-based lubes, to me, just seem runny and too "oily" to use on my genitals, so i would really only use them for massage purposes.
I've use water based lubes for years, mostly because they're safe to use on my ears to help with stretching and massaging the tissue, as well as on/with other piercings. I find the clean up, used on my ears or on my genitals, is much easier - although they can be a little more sticky than some other lubes. They're also so much safer for those with allergies and for use with any and all toys.
