Over the years my wife has definitely been able to accommodate me inside her more easily - when we first we met I was apparently much bigger than the only other cock she had experienced. I believed her as she was remarkably tight and I would make her moan just sliding inside. These days though I slip inside within seconds and any moaning seems less spontaneous and simply exaggerated for my benefit I suspect she would love it if I was thicker.I was going to say something like that but didn’t want to sound rude. But as you say middle-aged and older mothers have often lost that tightness through multiple childbirths and are often carrying excess fat, so to get the same sensation of depth and stretch that they enjoyed in their younger years they need a cock with more length and girth.
