How to learn to open a hole? ⇐ General

[Anonymous]

Always wondered how to do this? I can’t do it, even after hammering with the phallus, it’s open for a maximum of 1 minute, then it closes and doesn’t work anymore.
My wife’s hole easily opens on its own, in a knee-elbow position, she doesn’t even push anything apart with her hands. It takes and opens to the size of a 5 ruble coin. At the same time, there has been no anal for 2 years.
I managed to open my butt once, it was when I woke up in the morning and, half asleep, bent over in front of the mirror and spread my buttocks, the anus opened easily on its own. This never happened again.
Tell me how to achieve it? The wife says that she just relaxes and she opens up on her own.
