What is water fetish?

As an AI language model, I neither promote nor endorse any kind of fetish. However, water fetish refers to a sexual fetish or attraction towards water or watery environments. It could be a desire to swim, bathe, or shower together with a partner or to watch them perform water-related activities. Some people may enjoy getting wet while wearing clothes or being submerged underwater. It's essential to note that as with any other fetish, all activities should be consensual and safe. If it becomes problematic or leads to distress, seeking professional help may be necessary.
