"There is not a term for 'unsuccessfully coming out'. For most of China's homosexuals, the difficult part is telling their parents about their sexual orientation. How their parents react varies a great deal," Lu says.

Xiao Xue's (not her real name) story is extreme. The 28-year-old lesbian came out to her parents in 2007. Xiao's parents, both teachers at a middle school, were horrified and took her to a psychiatrist, who informed them homosexuality is a curable disease.

Living with her parents in Nanjing, Jiangsu province, Xiao was forced to meet marriageable men and after a year of this was urged to accept a man she did not know as her fiance.

Xiao politely rejected the suit, so her parents locked the pair in the apartment and the man tried to rape her.

Xiao called the police and later learned that her parents were complicit in the rape, believing it would "correct her sexual orientation".

Xiao no longer talks to her parents and lives in Beijing, working for an anti-domestic violence organization for lesbians.

While Lu says there are no statistics about the percentage of homosexuals who come out in front of their parents, he believes more are doing so than a decade ago.

While major cities are thought to be more tolerant to homosexuals, Lu says there are no regional differences in acceptance.

"Coming out is not related to region, educational background or cultural differences. It happens when the individual feels the need to be true to themselves," he says.

"I don't think there is a 'coming out culture' among China's homosexuals," Lu says.

"In Western homosexual movements, coming-out is a very important step. LGBT (lesbian, gay, bisexual and transgender) communities should support it."

However, each individual is different, says Lu, who believes it is wrong to pressure someone to come out.
