How can one safely engage in masturbation with water for added pleasure and sensation?

It is important to use clean water and avoid introducing any harmful substances into the body. One can experiment with different water temperatures and pressures to enhance pleasure, but it is crucial to be gentle and listen to the body's signals to avoid any discomfort or injury. Additionally, using a water-based lubricant can help reduce friction and increase sensation. Remember to always prioritize safety and hygiene when exploring new methods of self-pleasure.
