My wife and I have a great marriage, over 35 years but one of the reasons why is because we leave the sex to guys that are good at it .
Well said.
My wife and I have been married over 30 years, as well. We have a great marriage, but sex with her is primarily reserved for other men that have bigger cocks than me. I say "primarily" because she and I do have sex, but it's very, very seldom. I much prefer her having her sex with other, better and bigger men. She knows this and the fact that I like denial. So, over the years, I have gone well over a year without having sex with her.
I don't care for direct ridicule, but I love denial and mild humiliation. I love knowing that my wife prefers having sex with other men, instead of me. I also love the fact that many other people know this about us. I get all the sexual satisfaction I need watching, doing clean-up on her and him, and just knowing another man, with a bigger dick, is giving my wife way better sex than I can.
Also, my wife does like dp. My smaller size fits much better in her butt. So, I will join-in with her and her lover, from time to time, to giver her a dp. He and I have to put our junk right up next to each other, and I love seeing his bigger dick up against mine.
We actually started before we got married. My wife (fiancee at the time) started fucking my best friend. She was pretty confused when I told her how much I enjoyed it when they would fuck. He had a much bigger dick than me and he was very dominant.
He started coming over everyday and even spending nights with us. The three of us were sharing one king bed, so I got to watch the two of them have sex, up close. I would jack-off watching them, which meant I was done for the day. He, on the other hand, had much more stamina. He was fucking my fiancee, at least, 4 or 5 times a day and wearing her out. Before when knew it, a month had gone by without her and I having sex.
She brought up the fact that she and I hadn't had sex in over a month. I confused her, again, when I told her I preferred her having sex with him, because I knew how much she enjoyed it. Then, I told her that I definitely wanted to marry her, but I didn't want her to be concerned about the mediocre sex with me. So, if she married me, she would always have the freedom to have sex with other men whenever she wanted and as much as she wanted. She grinned at me and said "deal."
It's been that way for over thirty years. We have lost count how many lovers she's had. Many were one-night-stands, but we've had some that were long-term live-in lovers, as well.
So, to keep inline with the OP: Yes. All of my wife's ex's had bigger cocks than me and was a much better fuck than me.
