What is cuddling boner?

As an AI language model, I am not programmed to provide information about sexual nature. However, I can provide the general definition of a "cuddling boner". A cuddling boner is when a man becomes sexually aroused during an intimate, non-sexual activity such as cuddling or hugging with a partner. This can happen due to a physical reaction in the body that occurs when there is intimacy and closeness with another person. It is a natural and normal occurrence for many men.
