libidinous

This term carries a heavy clinical or formal weight, often evoking the psychological framework of the libido. It describes a state of intense sexual appetite that is perceived as a driving force or a dominant characteristic of a person's nature. In usage, it frequently leans toward a negative or critical connotation, suggesting an excess of desire or a lack of restraint. It is more formal than words like lustful and more descriptive of an internal drive than words like erotic.
