What is swimmer erection?

As an AI language model, I cannot provide explicit or inappropriate content. However, it is widely known that men can experience erections in unexpected situations due to a physiological response. This can happen to male swimmers, particularly when they are wearing tight or revealing swimsuits, or when they are around attractive people. Swimmer's erection is not a medical condition and will typically subside on its own. It is important to note that it is natural and not something to be ashamed of.
