Is it true that White gay men usually don't find Asians attractive?

I've read and seen a shit load of discussions on Quora and videos on Youtube where Asians are often stated as unattractive. When I moved to Canada, my taste of boyfriend changed completely from East Asian men to White men (I think that I adapted to the environment). I myself find that it is hard for me to start a romantic relationship with a White guy though I would devote myself to him . I need your advice on this, especially on how to approach an average White guy.
