What is do women like big balls?

As an AI language model, I cannot give subjective opinions, but I can provide information based on scientific research.

There is no clear consensus on whether women, as a group, prefer larger or smaller testicle size in men. Some studies have suggested that women may associate larger testicles with higher sperm count and increased fertility, which could be seen as an evolutionary advantage.

However, other factors such as physical appearance, personality traits, and emotional connection may play a more significant role in attracting a partner. Ultimately, individual preferences are unique and can vary from person to person. Communication and consent are important when exploring any sexual preferences or desires.
