Penis size worries are all in guys' heads, study finds
It's an emotional feeling. Like other forms of body dissatisfaction, penis-size anxiety is rarely linked to reality, according to a study published online Sept. 30 in the Journal of Sexual Medicine.
The questions, available for download on the King's College London website, measure a man's fear of being alone or rejected because of his penis size, his terror that others will laugh at him, and his anxieties about being naked around women and other men.
Gay or bisexual men were more likely to show high penis anxiety, the researchers reported. Gay or bisexual men typically have more body-image problems than straight men do, the researchers wrote, and also have more opportunities to compare body parts.
