And yet when they had it all, the empire fell appart. There's a saying here in Portugal that "those who want it all, end up losing it all". Now, this is not to say that one shouldn't strive to become better in every aspect of life. One should!
However, there's that "little" thing called sensibility, common sense, good judgement, or whatever you wich to call it, and it should be as important as your ambition. If your wife already told you to not grow any bigger, and if you want to maintain a steady, respectful, faithful, long term relationship with her, my advice would be to respect her wish. That doesn't mean you have to stop Penis Enlargement altogether. You can still perform lighter routines that won't exactly get you any noticeable gains, but still contribute to the overal health of your penis and your performance in bed.
Penis Enlargement is mostly a personal thing, yes, we do it to feel more confident. But let's face it, there are only 2 things you can use your penis for: taking a piss and having sex. Does having a bigger penis make sex more enjoyable TO YOU? Apart from the psychological factor, I'd say it won't make much difference to you. Therefore, the other physical reason we want to have a bigger dick is to provide a more enjoyable and pleasurable sexual experience to our partner. So, if your partner specifically tells you that you getting bigger will NOT make ir more pleasurable and enjoyable, what's the point in continuing? Is it so you can jerk off with 2 hands instead of one? Are you planning on enroling into vault poling?
Penis Enlargement is not all about size. To me, the fact that someone can get harder erections from jelqing or keggels (just to name an example) is a far greater benefit than adding inches. It's a matter of health. And I bet the majority of men wouldn't trade an average healthy dick for a big impotent one.
To add to this, I believe that one of things that contributes to our self esteem in Penis Enlargement, is not just that we have a bigger dick, but most importantly, that we created it ourselves, we got our bigger dick through hard work and dedication over long hours. That gives us a sense of accomplishment along with the added inches, it makes us feel like we have overcome an "obstacle", we have attained something valuable and rare.
So, although I wouldn't say that size is overrated (it is OVERrated but it does have its importance), it is just one part of Penis Enlargement.
Once some guy told me that he thought Penis Enlargement meant Penis Enhancement, and not Penis Enlargement. I believe this is a better perspective on the subject.
Just my 4 cents
