18 Harsh Realities of Modern Dating - Macken Murphy
Quick Overview
The ideal penis size for a long-term relationship, according to a study using 3D models, is 6.3 inches in length and 4.8 inches in circumference, though men overestimate their own size by about 20%, meaning the average man is significantly smaller than he reports, and while ideal preferences are high (e.g., 6'2" height equivalent), only about 27% of women report breaking up with a man at least partially over size, usually because the partner was too small.
Key Points: The gold standard study on penis size preference used unlabeled 3D models, finding women preferred 6.3 inches in length for long-term relationships and 6.4 inches for short-term relationships. Preferred circumference was 4.8 inches for long-term and 5 inches for short-term relationships, which the speakers note represents a significant volume difference compared to length discrepancies. Men overestimate their own penis size by about 20%, meaning the actual average erect size, according to a meta-analysis of 17 studies, is 5.16 inches, placing the preferred 6.3 inches near the 95th percentile (similar to being 6'2"). Most women surveyed had never seen a penis as large as their ideal preference, exhibiting a preference bigger than they had experienced, similar to height preferences. About 27% of women reported breaking up with a man at least partially over his size, with the vast majority of those cases citing the partner being too small. One factor influencing breakups due to size is physical discomfort, as being too large can cause pain by hitting the cervix, suggesting women may have more latitude on the small side than the large side regarding physical thresholds. In a separate discussion about body image, men and women diverged on preferences for a transformed physique: women strongly preferred the less lean 'dadbod' version of Ollie M, while men strongly preferred the leaner, more muscular 'after' photo.
Context: The discussion centers on Macken Murphy presenting findings regarding women's penis size preferences, using a specific scientific study that employed 3D models to bypass issues of misreporting that plague pen-and-paper surveys, especially given men tend to overreport their own size. The conversation expands into broader territory concerning ideal mate preferences, physical attributes like height and body composition (leanness vs. muscularity), and how these stated preferences align with behavioral outcomes like breakups and intra-sexual competition standards.
