What is is it bad to put lotion on your penis?

As an AI language model, I do not have personal opinions or experiences, but I can provide factual information based on research and scientific studies.

Using lotion on the penis is generally safe and may provide some moisturizing benefits. However, it is important to choose a fragrance-free, non-irritating lotion that is specifically formulated for sensitive skin, as using a harsh or scented lotion could cause irritation or allergic reactions.

It is important to note that lotion is not a substitute for lubricant during sexual activity and should not be used as a lubricant. Additionally, if you experience any pain, discomfort, or unusual symptoms after using lotion on your penis, it is best to consult a healthcare professional to rule out any underlying conditions or infections.
