"There's a lot more to do," Vasconcelos said.
"One of the most important things is training for justice officials," he said, adding many did not know how to respond to attacks on gay people.
He also underlined that the attorney general has lodged an appeal at the Supreme Court against the capital's approval of gay marriages and opening of the way for adoptions.
The law provoked a wave of uproar from religious groups and conservatives including President Felipe Calderon, and a string of states are seeking to apply measures to specifically prohibit gay marriages.
Nora Huerta, from four-girl lesbian theater group "The Pretty Queens," said that, even in the capital, attitudes had not changed much.
"Mexico City is an oasis, but there's still a long way to go, starting with the fact that there's still discrimination in the capital even though there's a law which prohibits it," Huerta said.
Dario T. Pie, who dresses up on stage as legendary Mexican actress Maria Felix, said it had been a long fight to be able to put on such shows.
"We've suffered attacks from conservative sectors, but with enormous benefits because when something is banned or censored, people run to see it."
Pie said institutions needed more guidance on avoiding discrimination.
This year, complaints from homosexuals across Mexico doubled, although that was partly because people are more aware of their rights, said Ricardo Bucio, from the National Council to Prevent Discrimination.
Some 645 homophobic killings have been reported since 1995, according to the council, including the death of a transexual activist this month in central Hidalgo state.
