IMO, Yuri Dominates yoai, lol most Guys like Girl + Girl Action, lol that is Hawt, lol while Yoai "AKA Guy+Guy" Can be a bit disturbing for guys, but got Girls Yoai is liked more, lol.
It's like this
Girls like Yoai
Guys like Yuri
Any other way would be for thoes who are Gay, Lesbian, bi, or have intested in the same gender as themselves but don't feel open to consider any relations to that in real life situations, *AKA the wanna-bees but cant's*
This is a very vague subject and can go with very much debate.
