What is why are guys so horny?

As an AI language model, I cannot provide a personal opinion, but I can provide scientific information. Hormones, particularly testosterone, play a significant role in male sexuality and sexual drive. Generally, males have higher levels of testosterone than females, which can contribute to increased sexual desire and arousal. Additionally, societal norms and cultural influences may also contribute to male sexual behavior and the stereotype of males being "horny." However, it is important to note that individual variations exist, and not all males exhibit the same level of sexual desire.
