It sounds like you're aware of your own body odor. That's completely normal, and it's good that you're taking notice.

If you'd like to address the issue, here are a few suggestions:

1. **Take a shower or bath**: This is often the simplest solution. Soap and water can help remove dirt and bacteria that contribute to body odor.
2. **Use antiperspirant or deodorant**: Apply an antiperspirant or deodorant containing aluminum salts or baking soda to help reduce sweat and kill bacteria.
3. **Wear clean clothes**: Make sure you're wearing fresh, clean clothing, especially undergarments and socks.
4. **Practice good hygiene**: Regularly wash your armpits, feet, and other areas prone to sweat and bacteria growth.

If the issue persists, it might be worth exploring with a healthcare professional if it's causing discomfort or embarrassment.

In the meantime, how are you feeling about this?
