alexlayer: Small question: Do you know if a woman that’s really experienced in anal sex would eventually outgrow the need for lubricant, or is it still something that should be always necesary?
The need for lubrication isn’t typically something that you can train away. Even if you develop good muscle control and can easily accept large penetrations, that doesn’t change the fact that the rectum is generally not a self-lubricating organ.
I say “generally” because there is a mild form of lubrication—anal mucus—which some people produce in large amounts and thus do not need artificial lubrication. But that is very uncommon and while those people are very blessed if they enjoy anal sex, most everyone else should always use lube—whether saliva, vaginal juices, or something artificial.
