I'd never bought lube before this, never needed to, but upon entering the toy world, I thought it was better to be safe than sorry.
I love it, espeeeecially when it comes to anal play.
It lasts long enough, it doesn't stain, it doesn't smell, it isn't really sticky or greasy or anything like that. It just... works, by doing exactly what it's supposed to.
A little goes a long way, and it's easy to clean up afterwards, too.
It also isn't irritating at all, and I'm sensitive all over, so that's a bonus.
Plus, the bottle is just cool. But the water-based is the reason I bought it. It's great.
