> If I remember right, J-Lube was originally a veterinary product, but it’s safe for humans. One advantage is that is mixed from a powder so can be made as thick or thin as the user wants. It is the preferred lube for fisting (so I hear) which is not dangerous if done correctly and prudent precautions are observed (or so I hear).

I’m not coming down on your post, and I’m not judging the practice. But while a fisting or two may not be dangerous, I’m not sure I can be convinced that repeated practice won’t cause lasting damage.

😕😕 What’s the significance of that particular date?

Just that it isn’t “Jul 2017”. It is very much a drive-by type of post.

I almost edited it to “raises fist”, but my (questionable) good taste prevailed.
