Not at all. I was married for 25 years to a lovely lady and by the time we split she had a big vagina. She never liked talking about it as she felt embarrassed how big it was but she was always the first to ask for her big dildo or my fist. She has a new b/f now and she says that she is lucky that he has a very thick cock because he does not like fisting or playing with dildo's. I then met another lady who was really into fisting. She also had desire to stretch her puss further and we had lots of fun doing it. She was one of the few ladies I met that could take a fist without any lube or gel. My current wife is also huge. She was like that when we met 7 years ago and loves being so big. When she spreads her legs her puss gapes. She still has very good muscle control but if she does not tighten it she is huge and cannot feel my cock at all which is a big turn on for both of us. She can now take both my fists and she is very proud of it. So .. are you insane? Not as far as I am concerned. Enjoy it.
