I have to apologize, I'm not sure I totally understand the last part of your answer
But in terms of why I said no, it's not really an issue with lesbian sex in itself (I've played exclusive girl on girl games and man on man games), it's more a fact that I don't enjoy the LIs in a game messing around, no matter the gender or how they identify themselves. I've always been a fan of one on one; more personal, more intimate.
For some reason a bunch of games assume that we, as guys, will always enjoy lesbian scenes, so I think it's cool that JDOR bothered to at least ask in advance; even if in certain parts you're "forced" to see things that you won't particularly enjoy, but that's true for almost any story in existence.
I still have most of the game to play to form an opinionated view of the game, but I'm really looking forward to see what else is in store!
