When using body wash, soap, or shampoo as lubricant while masturbating, making suds as a result of the hand motion.

To engage in a shower session means to masturbate while taking a shower. Most of those who take on a shower session sit on the shower floor while they masturbate, due to the incresed difficulty of standing masturbation. Also, many of those who engage in shower sessions commonly use moisturizing conditioner or body wash as a lubricant. Although these two products are commonly used, shampoo is not used due to its tendancy to dry out fast on the penis.

Dad: "Why is that son?"
Son: "Because I haven't had a shower session in three days!"
