The water-based formula absorbs slowly enough that it doesn't get sticky halfway through, which was my main issue with other lubes. Being pH neutral is a nice detail too, no irritation at all.
I've used it for both massages and intimacy, and it never gets sticky or tacky halfway through. The water-based formula rinses off clean with just warm water, which I didn't expect.
The pH-neutral bit is actually why I switched to this one, and it hasn't irritated my skin at all after a few weeks of use. It doubles fine as a massage lube too, though you do need to reapply after a while.
