ImagoThe 20-year-old, who plays in the Swedish second division for Utsiktens BK, who are coached by his father Glenn, comes from a footballing family with his older brothers Tobias and Alexander both playing professionally too.
Hysen revealed that he came out to try and show that being a gay footballer is no big deal.
"I might not play in the top league, but I want to prove that there is no big deal if I'm a footballer and also gay," he told Offside magazine.
"If I perform as a footballer, then I do not think it matters if I like men or women."
Hysen admits that some people might have a problem with his decision but that it is their problem and not his.
"There will always be people who can't tolerate gay people, just like there are people who can't tolerate immigrants.
"A club might be interested in me and then the coach might change his mind if he finds out I'm gay, but that is his problem not mine."
England cricket player Steven Davies and Welsh rugby star Gareth Thomas both recently came out in high profile cases, but there are currently no openly gay footballers in England's top four divisions.
"It's totally sick when you think about it," Hysen said about the lack of openly gay footballers.
"It's so f****d up, everything. Where the hell is everyone else?"
Hysen's brother Tobias, a Swedish international with 15 caps, backed his brother's decision.
"Hopefully more people will have the courage to come out now after his brave decision."
