When it comes to porn videos, you can rarely find a woman with curly hair. This is because curly hair is a genetically determined trait, and the majority of women have straight or wavy hair. Although curly girls are rare, they do exist, especially in amateur scenes. Curly girls may seem like they belong in a different category in porn videos, but it's important to note that curly hair does not necessarily mean they have less-than-average-curly locks.
