tips for a newbie

[solceco]

Hi
I would like your frank opinion on what I can expect from a routine of manual stretching exercises (or even the use of an extender) to definitively correct a little curvature that I find unsightly and gain 0.5in in length so that I can say without lying that my cock is 8in long.
It's hard to know whether those who claim to have definitive gains are telling the truth or not.
Can manual stretching exercises be enough? If so, how long will it take?
What about the extender?
Does it work or is it all bullshit?

Research extenders. After years of vacuum pumping, I can honestly say I wish I had known. Everything I read says that traction extenders are the only scientifically and clinically researched and approved method for enlarging your cock in length and girth, while also correcting unwanted curvature.
