The hammam thereby represents a parasexual space for the unfolding of sexuality, one that helped fix the meaning of sex more than sexual acts themselves.
Also, the parasexual cycle, in which recombination occurs without meiosis, can function as an alternative for sex in imperfect species (Pontecorvo 1946; Snyder 1961; Davis 1966; Caten 1987).
These mechanisms are completely exclusive of the parasexual cycle, which has not been demonstrated to occur in nature.
