Zachary Quinto ''definitely'' wants to have children.

The 'Star Trek' actor - who is dating 'Glee' hunk Jonathan Groff - admits he does not let his sexuality put him off starting a family and is very keen to have kids eventually.

He said: ''I'm incredibly happy, I'm incredibly lucky. I definitely want kids. I want to share.''

Zachary decided to come out in October 2011, and is glad he did so as ''no good'' could come from him keeping his being gay a secret.

He told Out magazine: ''One of the defining conversations that I had with myself was that absolutely no good can come from me staying quiet about my sexuality.

''Literally, no good can come from it. But if I take the step to make the acknowledgement and be honest, so much good could potentially come from it.''

The 'What's My Number?' star previously revealed he decided to come out as a gay man after performing in the play 'Angels In America' - which discusses the effect of the Aids crisis.

He said: ''Doing that play made me see how fortunate I am to have been born when I was. And to not have to witness the decimation of an entire generation of amazingly talented and otherwise vital men.

''And at the same time, as a gay man, it made me feel like I - there's still so much work to be done.''
