Zachary Quinto says he has a "thrilling and scary" future ahead of him since coming out as gay.
The 34-year-old actor - who admitted he felt he needed to admit his sexuality to help contribute to "complete equality" following the suicide of homosexual teenager Jamey Rodemeyer in September - thanked his supporters but denied he is a "trailblazer".
He said: "I feel so incredibly grateful to all of the people who've reached out to me directly or indirectly or just in spirit and I feel really, really like my entire future is laid out in a different way and it's thrilling and scary and overwhelming.
"There've been people on this path who were much bigger trailblazers than me who did this at a time when it was even harder ... and if me standing up and making some kind of acknowledgement and declaration helps that, then I can't ask for anything more out of my life."
After coming out in an interview with New York Magazine, Zachary took to his blog to talk about the need for civil equality for every gay lesbian bisexual and transgendered citizen of this country."
He said: "In light of Jamey's death - it became clear to me in an instant that living a gay life without publicly acknowledging it - is simply not enough to make any significant contribution to the immense work that lies ahead on the road to complete equality. Our society needs to recognise the unstoppable momentum toward unequivocal civil equality for every gay lesbian bisexual and transgendered citizen of this country."
Writing on twitter, he added: "i have spent the day in awe of this outpouring of support and resonance. we. are. in. this. together. NEVER FORGET! i am deeply moved. (sic)"
