Fuck no bigger is not better ever for me.
Give me a parade of small and average cocks all day long and I'll be happy.
As soon as I see a big one I start resenting using a more expensive, larger condom.
I'm generalising slightly here, but in my experience of shagging several thousand men, very often the ones with big cocks are the most selfish, entitled lovers ever. They drop trou with a smirk and expect you to go "OMG babe, it's soo big, I'm wet already, please put it in me" 😒
Of course there are many men with large cocks who are great at sex and understand that when you say "There's no way we're going to be having penetration, sorry" then that's just life.
And yes it's about the girth not the length. I've had a couple of clients whose cocks were like coke cans. No fucking way am I putting that up me, mate.
