Having to do with bodily pleasures.
Example:
The news stories about students going on Spring Break focused as usual on the carnal pleasures associated with the annual ritual.
Carnal is sometimes used to mean "having to do with the human body," but more often it refers solely to the pleasures and appetites of the body. Most religions stress the superiority of spiritual enlightenment over carnal pleasures. Very frequently, carnal simply means "sexual," especially when the sexual activity is mostly physical in nature. Novels about Hollywood often rely heavily on detailed descriptions of the carnal adventures of their main characters.
