Ultimately, it's important to consider your specific needs and preferences when choosing between water-based and silicone-based lubricants. **

A society based on social classes is characterized by a hierarchical structure where individuals are grouped based on their economic status, occupation, and wealth. This system often leads to inequality and limited social mobility, as individuals are born into their respective classes and have limited opportunities to move between them. On the other hand, a society based on social estates is a system where individuals are grouped into distinct categories based on their roles and responsibilities in society, such as clergy, nobility, and commoners. This system was prevalent in feudal societies, where individuals were born into their respective estates and had specific rights and obligations based on their estate. Unlike social classes, social estates were often based on hereditary status and were more rigid in terms of social mobility. **
