Australian diver Matthew Mitcham says he's comfortable with his sexuality and being one of only a handful of openly gay professional athletes.

Mitcham came out gay in 2008 ahead of winning gold at the Olympics in Beijing.

The 24-year-old Mitcham will compete during the 2012 Olympics to be held in London.

Mitcham told The Sydney Morning Herald that he doesn't mind the attention over his sexuality.

“I certainly don't see it as a burden.”

“I never did, especially with how much attention the LGBT cause has been getting lately with marriage equality … and with how few openly gay sports stars there are around at the moment,” Mitcham said.

“Ideally I would like one day for sexuality to be as unimportant and uninteresting as hair color or eye color or even just gender in general. One day it will get to that.”

“But until it is easy for sports people to come out without fear of persecution or fear of lost sponsorship income and stuff like that, or fear of being comfortable in a team environment, I don't mind attention being brought to my sexuality in the hope that it might make other people feel more comfortable … in being comfortable enough about who they are in their sporting environment.”

Last year, Mitcham was named ambassador to the 2014 Gay Games to take place in Cleveland, Ohio.
