Fact check: Is 21x14 cm dick Big?

1. Summary of the results

Based on the scientific analyses provided, a penis measuring 21x14 cm would be considered exceptionally large compared to established medical data. Multiple comprehensive studies consistently show that average erect penis length ranges between 12.84-15.2 cm ^{[1] [2] [3] [4]}.

The most robust data comes from a systematic review analyzing 75 studies involving 55,761 men, which found an average erect length of 13.93 cm (5.48 inches) ^[3]. Another meta-analysis reported a mean erect penile length of 13.84 cm ^[1]. Even the higher measurements from a prospective study of 800 men showed a mean stretched penis length of only 15.2 cm ^[2].

The dimensions 21x14 cm would place this measurement significantly above the 99th percentile for both length and girth, making it extraordinarily rare according to all available scientific data ^{[1] [2] [3]}.

2. Missing context/alternative viewpoints

The original question lacks important contextual information about what constitutes "big" in practical terms. Research indicates that female sexual satisfaction may prioritize width over length, with 45 out of 50 females reporting that width felt better than length ^{[5] [6]}. This suggests that the 14 cm girth measurement might be more relevant to sexual satisfaction than the 21 cm length.

However, there's conflicting evidence about size preferences. One study found that reducing penetration depth led to an 18% reduction in overall sexual pleasure, suggesting that length does matter for some women ^[7]. This indicates that preferences vary significantly among individuals.

The analyses also reveal that penis size has increased by 24% over 29 years, potentially due to environmental or physiological changes affecting male genital development ^[3]. This temporal trend suggests that historical size standards may be outdated.

Most men worry about penis size despite having normal-sized penises ^[4], indicating that societal perceptions of "normal" or "big" may be distorted by unrealistic expectations.

3. Potential misinformation/bias in the original statement

The original question contains implicit assumptions that could perpetuate size-related anxiety and misinformation. By asking if these dimensions are "big" without context, it may reinforce the problematic notion that larger is inherently better.

The question also lacks acknowledgment of measurement methodology concerns. Research warns about volunteer and social desirability biases in self-reported measurements ^[4], suggesting that many claimed measurements may be inflated or inaccurate.

The framing ignores the medical consensus that most men have normal-sized penises and that extreme measurements like 21x14 cm would be medically unusual and potentially problematic rather than simply "big." Such dimensions could indicate underlying medical conditions or measurement errors that warrant professional consultation rather than casual comparison.
