If you have tried every method why not try doing it all wrong?
I'm serious.
When I first came here I read all the info's and advice, absorbed some of it then just went off, ignored everything and did my own thing. Apparently I have been doing it all wrong so don't know how I got these bouncy things in my bra.
I don't massage either and have never used a noogle thingy either but they grew anyway so just do your own thing, try that.
I would show proof but due to recent events I think it unlikely that I will ever post an image again. However if nothing works then F it, just go your own way and do what feels right. Everybody's body will react differently and your body will know what's right for itself. Experiment even if you think, oh this shouldn't be happening to me because everything I read says its wrong.
Do what feels right for you.
