I guess a decent pun.

Real answer? This was written by someone who clearly has never actually had anal, as competently done anal sex does not weaken the anal sphincter. This is the same naive logic as the guy who thinks he’s going to ‘stretch out’ his lady’s vagina, despite the fact that a vagina can safely pass a baby through itself.

It’s a kink, it’s messy and/or inconvenient. Porn has made it the be-all-and-end-all, but it’s just one more thing you can do.
