I use a mix of trex (Cheap UK version of Crisco) with sunflower oil first to coat my insides then J-lube. Find the first one stops the j-lube drying out as fast.

I was using this until recently when I realised it had sodium lauryl sulfate in it which is a skin irritant. It’s only usually used in thing that are washed off the skin fairly quickly so not sure about it in your rectum. I thought it was working well but then when I thought back I had been getting a bit sorer than normal when fisting.
