Little is known about the sexual functioning and behavior of
men anxious about the size of their penis and the means that they might use to
try to alter the size of their penis.
To compare sexual functioning and behavior in men with body
dysmorphic disorder (BDD) concerning penis size and in men with small penis
anxiety (SPA without BDD) and in a control group of men who do not have any
concerns.
An opportunistic sample of 90 men from the community were
recruited and divided into three groups: BDD (n = 26); SPA (n = 31) and
controls (n = 33).
The Index of Erectile Function (IEF), sexual identity and
history; and interventions to alter the size of their penis.
Men with BDD compared with controls had reduced erectile
dysfunction, orgasmic function, intercourse satisfaction and overall
satisfaction on the IEF. Men with SPA compared with controls had reduced
intercourse satisfaction. There were no differences in sexual desire, the
frequency of intercourse or masturbation across any of the three groups. Men
with BDD and SPA were more likely than the controls to attempt to alter the
shape or size of their penis (for example jelqing, vacuum pumps or stretching
devices) with poor reported success.
Men with BDD are more likely to have erectile dysfunction
and less satisfaction with intercourse than controls but maintain their libido.
Further research is required to develop and evaluate a psychological
intervention for such men with adequate outcome measures.
