Big cocks bringing orgasms is a myth.

Before I was married I fucked a lot of women. Most easily got off when I'd do oral, some got off when we fucked.
The cheating married women always had an orgasm, some said they rarely did with hubby at home. Probably the exitment of cheating ?
Married 25+ years now.
We get with a guy we know for mfm fun. My wife could easily cum when I'd go down on her or with a vibrator.
Our friend is 8+, I'm 6+. She cums easily with him when he's doing her. She can cum with me while I'm fucking her but only when he's with us and after she's cum with him. She gets REALLY turned on when he's with us. I think it's the whole thing that she's into, two guys taking turns with her, she seems to absolutely love it. I'm sure the size of his dick helps but I like to think the mental excitement is a big part of it.
Yeah, to your point, I think 50% of the orgasm or more, for many women, is mental. I wonder how often people who report their wife cumming like crazy on a bigger cock is primarily just their wife being extremely aroused by being with a new partner and the naughtiness of what she's doing. Nothing dampens lust like familiarity....

My wife hasn't been with another partner yet but, being over 40, she's recently started to have trouble cumming. I used to make her cum at least 2-3 times, every time we had sex in our 20s and 30s... now if she's tired or has been drinking, even 1 can be a challenge. I've tried bigger dildos, which she doesn't like that much as she gets sore quickly, vibrators, which work sometimes... what never fails though is porn. She never watches porn herself but if she's having trouble, I give her pornhub on the tablet and once she finds something she is into (usually a wife getting DPed lol) she's always able to cum.

So, while I imagine a bigger cock could be better in some ways, providing more feeling of fullness, I think a bigger part of it is mental.

It would still be fun for me to watch her take a huge cock though haha...

I think there can be an element of both. No doubt my wife enjoys the physical variety and particularly a big cock. She often refers to how deep inside she can feel it, 'like snake'. But there are definitely mental aspects as well. For her there is an excitement from the thought of being impaled on a big cock, of submitting to it, all mental. When she was a part time escort she says it was always an exciting boasting point to share with her girl friends that she'd had a big cock.
 
I would somehow disagree by experience. My wife had for about 8 Month a Lover who did have a pretty big dick. When my wife saw him first time in front of her first thought he will never fit. My wife’s first impression was wrong he did fit. When my wife had the first time sex with him I could hear groaning of pleasure and climaxing several times on him.

At some point he came out nude und asking for an ashtray. Even hanging soft and wet he had still an very impressive size, apart from it he was cut which did explain that he was able to fuck my wife that long.
I send him to the kitchen and rushed to the bedroom where i found my wife still with her open legs and a bit exhausted. I commented that I could hear her climaxing she answered with a little smile. Oh dear with his size there is no other choice.
Her new lover came back with cigarettes and ashtray and I left them alone.
About half an hour later i could hear my wife lusty groans mixed with what i identified as yes, yes... and this time she was screaming her climax.

In this time I had my office about 900 miles away and was flying in every weekend to see my family. Her new Lover which we both called meanwhile "donkey dick" as a pilot had no normal weekends. My wife saw him 2 to 3 times in a month for one night while I was still away.

Sometimes when he was in town during my weekend he texted us and I picked him up from the airport hotel to spend the night with us. We than fucked my wife both where I usually fucked her first because he stretched my wife penetrating her and I would have had no chance after him.

She went on a short vacation trip with him where she took her notebook along. Sometimes she put that notebook on the desk of the Hotel room and I could watch them fucking. Oh my wife loved it to be fucked and looking in her sexual excitement at the screen of her notebook to see me rubbing my dick.

My wife ended this relation after that trip because he was hormon controlled and it was just too much for her. She returned what she called "Over killed" and had for some time no desire for Sex
