I agree with you, I think the answer is clear. With any anxieties, it is alleviated when there is success in some form.
I have many anxieties over the years, such as, can I get the price I want when selling house, or can I do this new job. Will people understand and appreciate my input in the workplace. and so on and so on. Did I say the right thing........ - But we try and cope and move on in some form with or without success.
but all can be debilitating. Penis size is just another.
I think it is where success springs from which can change self perception on adequacy of penis size.
Finding a partner with no issue on size is possible, I have experienced this. Surgery and PE can bring success also, as has been seen on this site.
Perhaps therapy brings change.
OR even being in a situation where issues of survival take higher concern than penis size. I am not sure a starving teen in any part of the 3rd world has attention stuck on penis size, nor his partner is worried also.
It is relative to circumstance.
There is a lot of combined experience on this site to draw from, as well as somewhere to express your thoughts, and read those of others, which I think does alleviate anxiety too.
