Probando con mi ex-pareja el sexo anal

It seems like a lie but now that we've stopped being a couple, we're having a better time and we're not arguing all day every day, it's also true that we're not together all day like before. Now, what is curious to me is that sexually we enjoy ourselves more now than before and we do things that were previously unthinkable, for example, my girlfriend no longer has an aversion to anal porn when I tried for years and always got a no in response... there are those who understand the aunt friends?
