I daresay I have plenty experience with lubes; I also have a sensitivity and thus am pretty choosy.
It's important to consider what material you're playing with;
- silicone, metal & glass is non-porous and needs a lubewith great wettability (that is a term). Silicone is the worst to stick to (lowest surface energy, glue that sticks to glass or metal sheds off silicone)
- vynil, tpu/tpr is porous enough that lube pockets are created.
- flesh is just perfectly porous and thus least demanding.
For silicone the above is my preference.
I have used:
J-lube - great, but a bit messy and contains saccharides
X-lube - better but messy
Silicone lubes: they do say silicone lube is NOT compatible with silicone toys and:
- pjur does create an adhesion layer and seems to bond with the toy. Very vigourus washing was required but no lasting toy damage.
- I found Longtime by german manufacturer Ritex which is perfectly compatible with silicone, but will cause some stick-slip (a firm #2).
The above hybrid lube contains silicone which is water-soluble. Very soothing, no stick-slip and aids a lot in recovery after an intense session.
I am not even discussing water-based lubes since they contain preservatives, and dessicate the cells (the hybrid lube above does dessicate but the effect is much, much less compared to water-based.
