Studies of penis size based on self-reports

found that the average size of an open penis ranged from 6.0 between 6.3 inches (Bogaert Hershberger and Boogaert 1999; Gebhard & Johnson, 1979; Harding & Golombok, 2002; Jamison & Gebhard, 1988; Richters et al. 1995; Smith et al. 1998 Templer 2002). The average of 6.4 inches as reported in the current research (sexually experienced and inexperienced males together) is similar to the findings of these studies. Homosexual men self- report even larger erect penis lengths (Bogaert & Hershberger, 1999; Coxon, 1996; Grov, Wells, & Parsons, 2013).

In four studies, in which the measurements of penises that were fully erect were taken by sex scientists and sex researchers, the average length of the penises was 5.36 inches (n1/4541 da Ros and co. 1994; Schneider et al. 2001; S engezer et al. 2002; Wessells et al. 1996). The self-reported average penis length by males who had been sexually active in the current investigation (6.62 inches) was 1.26 inches higher than the average.

A significant proportion of males who have had sexual experiences could be classified as excessive over-reporters (with 30.77 percent reporting penis lengths as high as 7th inches, and 10 percent reporting their erect penis length as at least 8 inches). Studies have shown that a majority of men would prefer they had a bigger penis (Johnston and co. 2014; Lever et al. (2006); Tiggemann et al. (2008)) and the current findings suggest that self-reported the size of their penis are affected by social desire. The extent of the relationship with social desire could be higher when it was possible to determine actual errors scores (self-reported penis length divided by the actual length of the penis) similar to what is used in studies on nutrition (see Archer et al. (2015)).

The distinction between experienced and sexually inexperienced men in self-reported size of their penis is not reported before however it is possible that over-reporting is more common for men who have been through the process, leading to a stronger correlation within that group. We believe that the distinction between the two groups could be because of a higher level of masculinity, sexual competence and prowess of experienced men (Tiggemann and co. (2008) Wylie and Eardley, 2007).

With regards to limitation, this study utilized an uninvolved sample of male college students and it’s not certain if similar results could be observed in different categories. Men were separated from female students in the test, however, with many males comparing the size of their penis with masculinity as well as sexual competency and strength (Tiggemann and others. (2008) Wylie and Eardley 2007) In addition, the massive testing could have affected the men’s perception of themselves and caused them to embellish their responses more than usual.
