Oil-based lubricants can be used for various sexual activities, including masturbation and intercourse. They are known to be long-lasting, making them ideal for extended sessions. They also tend to be thicker and provide more cushioning and lubrication, which can increase comfort during sex. Oil-based lubricants can also be used for massage and provide a slicker, smoother feel compared to other types of lubricants. Additionally, some people prefer oil-based lubricants because they are made from natural ingredients and are free from synthetic additives.
