>>1540972he's never clarified it. like you say, it's somewhat up in the air. so it is playing the is he isn't he game.
if someone asks if joey graceffa or connor franta or troye sivan are gay, i can say yes they are and point to where they've said it. if someone asks if thomas is gay, bi, pan, i can't say yes or no, he's never given any clarification on it, despite being asked about it several times.
if when someone questions a youtuber's sexuality no one can actually give an answer and point to where they've said it, then it's still a "mystery", even if it's an open secret type of thing, like colton haynes.
if someone asks danisnotonfire's or amazingphil's sexuality, i can say they're bi, because a few years ago they said so on formspring.
a lot of thomas' hinting has been through vine skits and that's not very reliable, since they can be assumed to be comedy and not based on his actual sexuality
