If Shu-ya is gay... He's always made my heart skip a beat... Especially watching him in the Rule PV.

I don't really care about the others, except Gomi and Subaru. I'm happy maro is married (?) but we really don't hear enough about him or zin--it's like they're there when they have to be there and not when they don't have to be there. And even with Subaru, he's not right up with there with Shuya or Gomi... at least to me. I just don't hear enough about most of her dancers for it to really matter to me, personally.

So I'm inclined to believe that Shuya is at least bi, and that Gomi is 110% gay.

Bear in mind that they may not go public with their sexuality because it's still very taboo for people in entertainment to have different lifestyles.

Japan, Korea, China... are all two types of people in one person: The person who fits into society and the person who is their own individual. So, they might be more than comfortable with their sexuality in their private lives, but publicly do everything to stop it from becoming news. It's why you almost never see AV stars do anything else with their lives: They will always be known for being AV, and it's hard to break that label once its attached to you by everyone in society.
