It sounds like you've discovered a fluid-filled sac on the underside of your penis, which understandably raises some concerns. While it's natural to feel puzzled, many conditions could explain what you're experiencing, especially without accompanying pain or discomfort.

Common Causes:

1. Cysts: These are typically non-cancerous and can appear anywhere in the body, including the genital area. They may be sebaceous cysts, which contain oil, or other types of fluid-filled sacs.
2. Pearly Penile Papules: These are small, harmless bumps that commonly appear around the glans of the penis and are often mistaken for cysts.
3. Hernia: Less common, but could be a development of a hernia if the sac feels soft and is located in a certain area.

Since the sac is not causing you pain, it could simply be benign. However, since you have concerns, here are some prioritized next steps you can take:

Next Steps:

1. Observe: Monitor the sac over the next week or two. Look for any changes in size, shape, or sensation, and note whether any discomfort develops.

2. Maintain Hygiene: Keep the area clean and dry to prevent any irritation or potential infection. Gently wash with mild soap and water during your daily hygiene routine.

3. Avoid Irritation: Wear breathable underwear and avoid tight-fitting clothing, which can irritate the area.

4. Consider Keeping a Health Diary: Write down any additional symptoms you notice, such as changes in size or occurrence of discomfort.

5. Research Further: If the sac changes, causes discomfort, or if you have ongoing concerns, seek professional advice for an accurate diagnosis. Knowledge about what to look for can prepare you for a conversation with a healthcare provider.

Remember, while it's good to be cautious, many conditions are benign and completely harmless. Take care, and feel free to reach out if you have further questions or concerns.
