Porn stars are statistical outliers, not the norm; men are more likely to be over 6’3” than to have a penis longer than 7.5 inches.
It also "appears" that men may be inclined to having poor self-perception, regarding their penis size.
Males may quite easily underestimate the size of their own penis relative to that of others, because of the foreshortening obtained from looking down, due to repeated observation of atypical penises in pornography, or because of the accumulation of fat at the base of the penis. A survey by sexologists showed that many men who believed that their penis was of inadequate size had average-sized penises.
Given that men are the main consumers of pornography, why does pornography feature so many men, out of the norm for penis size?
Would it be more appealing to men, if the men starring in porn, had average sized penis? what is the psychology behind using men with such, abnormally, large penis?
