I personally prefer silicone-based lube for back door play. Lasts a LOT longer, doesn’t get sticky (can get dry, but nowhere near as quickly as water-based, in which case, just apply more lube,) and the overall glide just feels better imo. Clean-up is a little bit more intensive. Just a light scrub with soap and warm water, instead of a quick rinse or wipe. Toy play is a good warm-up. Just make sure your toy is specifically compatible with silicone-based lube or else you risk major problems.
