Many do, if there husbands are not well endowed or don't have good technique. That said, after a woman has had children they find the need for a fuller vagina when being fucked.

Hi, I am not sure I can help you as ours look a similar size. But When I was young and at college I did have a 3 some with an older couple who were in their late 40s and I was about 21 at the time. The women wanted more sex and a larger penis. We had a lot to drink one night and talked about it. Turned out her husbands dick was only 4" when hard. I mentioned that mine was a little over 6" hard. She wanted to see it so we went back to their flat, all got naked and I had sex with his wife while he watched and had a wank. They were good fun and grateful and we did it a few times. But as others have said they were ready to try it.

Hell yeah! I wish my wife was adventurous. I'd love to watch her having sex with other guys!

i have let my wife fulfill her fantasy of being with another man ( more then once ) and she was very grateful.
as long as you can handle it why not let yours be happy also !

My wife has always fucked other men who are bigger and thicker then me. It's not that she's a size queen, it's just that she needs bigger and thicker (and lots of stamina) for her real pleasure.

Sharing your wife is an intensely satisfying thing, but you and she have to be on the same page about it, and you can't be a jealous type or it won't work.

do it

I would love to let her use my big cock. She would really know that she had been fucked.

Go for it!!! But only if you two have a strong and healthy relationship. My wife had a number of wants sexually. We became swingers and she was able to achieve them. She wanted a large cock, she wanted a black guy, she wanted a woman, she wanted a gang bang and lots more. It started with just wanting to experience sex with another woman. But once we got involved All of her other wants started to cum out. So I set them up for her. Bonus was I also got to do some of my things. We just look at it as adult fun, just sex. It has nothing to do with love as that is our personal thing. In the end, it is 'us' that end our time together. I have even loaned her out to guys for the night. She enjoys it and I find it damned hot!!
