I'm not into gay content, specifically, but I found my way here because I'm bisexual. I enjoy the game a lot with the content we have and what we're getting seems great. It would just be nice to get a character or two down the line that's into non-standard stuff.
And don't get me wrong, I don't want it to be forced on people. Kevin, for example, should have the option to be turned down at the start of the relationship. No sexual advances will be sent towards the MC if he's turned down early on. Whether that character has a story-line if turned down would be up to DC. But if not turned down, it leads to a story like other characters have.
The same goes towards fetishes. You should have the choice during a scene to not do it. If you're not into footplay/anal/watersports/etc., don't choose it. I don't want people to be forced into watching content they find unappealing.
