We use O'My. This is a blurb from their site,

[
Made in Vancouver and in keeping with West Coast sensibilities, O'My has all-natural botanical ingredients including hemp, which binds the water molecules to keep them from drying. Also available in pump size, this is a great lube to consider for something that stays wet along time, with minimal taste, and a reasonable price tag. ]
Its super sliippery and doesn't dry out fast and get sticky like KY or a lot of others. Maybe best of all, it tastes good!
