Vaseline Enema

Just saw someone in FetLife who gives "Vaseline enemas"... actually uses Vaseline not as the lubricant but as the solution... never heard of such of a thing but intrigued. Can anyone who has experience with this elaborate?

That's a new one on me (vaseline enema). I can't even begin to imagine how that'd do much for you, and I wouldn't think the mess would be worth it. But to each their own.
