Yes,we really need to eject after the usage of a usb drive

YES, It also helps to prevent files and data corruption.

You should probably always eject a drive before removing it, even if the context menu doesn't have an eject option. Mac and Linux will always provide you a way to eject a drive, but like you said, Sometimes Windows doesn't have an obvious "Eject" button for certain drives. On Windows, click the "Safely Remove Hardware" icon in the system tray, choose your drive from the list, and then remove it once it notifies you of its safe removal.
