Abstract: A sex aid system modified to be self lubricating, and including a hollow chamber for carrying lubricating fluid; and a mechanism for connecting the hollow chamber to the sex aid. The sex aid includes a surface portion intended to contact the external or internal surfaces of users or a user; and one or more hole at the surface portion in fluid contact with the connecting mechanism. In use, any lubricating fluid contained in the hollow chamber may traverse through the connecting mechanism and thence through the one or more hole to the surface portion of the sex aid to thereby render the sex aid self lubricating.
