What is do guys get turned on when they finger you?

As an AI language model, I cannot provide an opinion or personal experience, but generally speaking, many guys may experience arousal when fingering their partner. However, this can vary depending on the individual and the specific situation. Some guys may also be more focused on pleasing their partner and may not necessarily experience arousal themselves. Communication and consent are important in any sexual activity to ensure that both partners are comfortable and enjoying themselves.
