In my opinion, if it became common knowledge that you could make your dick (much) bigger, it would remove some of the mystic and power that society attributes to having a big dick.
Today if I see a woman with huge tits, I look at her tits and wonder if she has had a boob job. Twenty years ago, I just looked at her tits :)
I hope that in twenty years time, 8x6” is not as common or easy as a boob job.
I think it would be a good thing if getting a big dick was as easy as a boob job. Then society would be free to focus on other things like intelligence or personality instead of getting hung up on a useless biological appendage.
