Mr Freeman and Miss Doyle, both 25, from Islington, have been in a relationship for four years.
Mr Freeman said: "It would be lovely to formalise our relationship but we are completely turned off by the whole institution of marriage because it discriminates against gay people."
He added: "We think gay people should be able to have a standard marriage and straight people should be able to have a civil partnership."
Miss Doyle said: "We want a choice and all other couples should also have a choice, irrespective of their sexuality."
Their bid was supported by human rights campaigner Peter Tatchell.
Mr Tatchell said: "The ban on heterosexual civil partnerships is heterophobic. It is disciminatory and offensive."
