Intriguing posts. I would like to give another small penis perspective. I am a married man with a sub 5" penis. I am my wife's only lover, but I often wonder how she would react to a larger cock. I am able to bring my wife to an orgasm most times and our sex life is still sizzling.
Doesn't sound like you have any problems.
My wife did not select me for my size or lack of size. However, I think if she had both she would select a larger one.
How do you know?
A few years ago I surprised her with a cuke in some foreplay. We live a real conservative lifestyle, so this was a real gamble with me. The cuke was over 9" long and 6" around. After teasing her for a while with it, she hesitantly asked if I would tease it inside of her. Slowly and patiently I eased it in. Once that cuke reached beyond my reach I noticed a change in her. I know some will think I imagined it, but her eyes closed and she acted much more aggressive than usual. After I inserted an inch beyond where I ever entered she let out the loudest, deepest, most lustful moan I have ever heard her make. Jill took all 9" and orgasmed hard.
And the awesome, powerful orgasm she had was with you using produce on her, not some other guy's huge cock.
Sure, part of this could have been something new and daring, but it really enforced my thought that if given a choice that a woman would like a larger cock, as long as he was skilled and gentle with it. No one really likes pain. To answer your questions, yes, it was odd to enter her afterwards, since she was no longer tight for me, but within a few days I would not have guessed she had something that large in her.
I always thought vaginas snapped back quickly unless the stretching was repeated. Of COURSE she's gonna be stretched out after you stick a cucumber in her! I had one girlfriend who was never tight for me (or anyone I suspect).
I wrestle a lot with this subject. My wife is very hot and sexy, many of my friends have told me so. Brunette, 36DD, and a face that you can get lost in. I feel that she has given me anything I could have wanted and she is getting a bit ripped. Oddly, I enjoy stories where women are exposed to their first big one.
You're lucky to have such a hot wife. You said in the first paragraph that your sex life is sizzling. If you read nothing else I write, read this: If you think it's somehow your duty to go recruit some hung stud to fuck your wife, realize you're opening pandora's box. Few relationships can handle bringing another party in. You've already said how wonderful your relationship and sex life are. You sound like you have it very, very good. If your wife wasn't into you, you'd know it by now. Sex would seem like a chore and she'd drop subtle little hints.
Sorry to bore you. Most of you guys on here are very lucky, indeed.
There are other ways to be lucky. I wouldn't know how it is to have any other kind of cock. I have a good friend who is a famous artist. I think he's about your size. One day he said to me "I'd love to know just for a weekend what it would be like to be you and have your big dick". I replied. "and I'd love to know what it's like to have amazing talent like yours" Men obsess way more about dicks than women do. You're truly a lucky man. Don't fuck it up.
