Hello.
This has more to do with tolerance than statistics (by the way, if it's obtained by surveys, in a world full of lies, it's not accurate anymore). If people were more understanding and less egoistic/self centered, there would be more games with a wide diversity of kinks instead of specific ones. We should ignore others (or debate with them) instead clashing with/hurting them. But apparently, it's becoming a worldwide sport.
You can add any game that offers the possibility of gay and straight content together, with the straight crowd asking for the gay content to be removed (like in Rebellion : the beginning), even if it's avoidable, even more if the straight content is in the minority like in Lust for Adventure or Medieval Times. Finding a bi game has become a rarity.
Good continuation.
