Wife keeps asking about anal sex with other men

My wife has been going through perimenopause, and all I can say is wow.

Since January, my wife asked about sleeping with other men, which we agreed, never on her own, but she has slept with 2 other men this year.

Also this year, my wife asked about trying anal, I had asked years ago and she got angry at me for even saying it, and now she asked.

Anal sex has become normal between us, but she has never had anal sex with other men, its not like her fantasies did not include anal sex with other men, but she didn't sound serious about it and didn't even bring it up.

But now recently the question has come up and not so sure about it.
