You said it :My wife has quite a large/loose pussy and she is quietly rather proud how large it is. She was less so when we first met, and was a little embarrassed about buying very large dildos, but these days, more than proud of it. In saying that, she still gets a little self conscious about it when with a new gent, worrying its too loose for their liking, but not one ever has said anything negative.
My ex wife also had a very loose pussy (loved being fisted and could even fist herself) but she never once gave a fuck what anyone thought, in her mind, cocks were only ever too small, not pussy's too big
