Penis size preference is a complex topic influenced by various factors, and research indicates there's no universally "ideal" size. Studies reveal mixed results, with some suggesting women prefer slightly larger penises than average, particularly for one-time sexual encounters. A 2015 study using 3D models found women preferred a length of 6.4 inches and a circumference of 5.0 inches for short-term partners, compared to 6.3 inches and 4.8 inches for long-term partners. However, these preferences are only slightly above the average erect penis size, which studies place around 5.1 to 5.5 inches in length.
Girth may be more important than length for many women, potentially due to increased stimulation of vaginal walls. Other factors, including emotional connection, sexual technique, communication, and adequate foreplay, play significant roles in sexual satisfaction. Some studies suggest that overall male attractiveness, influenced by height and a V-shaped physique, can also impact penis size preferences. It's also worth noting that exposure to pornography may lead to unrealistic expectations regarding penis size.
