I read the full-text article. Some parts of it are poorly researched. For example, the review of men’s and women’s attitudes toward dicks relies mainly on an Internet survey (a tough place to gather a “random sample”), while the estimate for average erect length relies largely on Kinsey and other self-report data. And the part of the article about natural PE is, well, entertaining:
SELF-HELP SOURCESInevitably, many men, rather than seek formal
medical help, prefer to use other sources of
information, but might then seek medical
advice. The Internet is a rich resource of
sources offering to help men ‘increase their
manhood’. Inevitably, there are no efficacy
data relating to most of these treatments
(especially the many pills and lotions
available). Common sense advice can be
found by some retailers, including ‘bulge
underpants’ and swim shorts, body and
genital hair trimming or shaving, the use of
‘hot towels and wraps’ and ‘jelqing’. The last is
an ancient Arab technique whereby the hand
pulls on the penis causing stretching (and
effectively self-focus work encouraging
psychological acceptance of the penis, which
will change in size and shape during the
process) and is recommended on many
websites. Some websites advocate that ‘small
is beautiful’ and that the smaller penis can be
celebrated by both the man and his partner.

The focus of the article is describing “small penis syndrome,” so these research lapses are understandable in my opinion.
