If one of my ladies is with someone else, I don't care if it's m or f - it's all the same to me. I don't even want threesomes or group sex. Of course, in games with paths / multiple routes, if there is a lesbian couple I'll just avoid them both. (Nothing against lesbians, but I don't want to watch, join them or split them up so...). This doesn't feel like it's gonna be that kind of game though (where I can just not have a relationship with either part of the lesbian coupling).
