While I lost my saves, and had a start over, and have not met the new people yet, there was not one lesbian in the entire game, as far as I saw.What I've disliked is that many of the cast were either lesbian or Bi's and there was a big emphsis on it in the story (Of course its my personal taste, you do you). I don't have anything against lesbian content, but it was too much and it was too empesised in the story. Case in turn Cath,Gabi and the other characters that flirt with this idea. Sometimes the idea that a character is a lesbian or Bi is overtaking the other qualitys of the character for example Cath and it seems that all of her personllity revolves around her sexuality which in my opinin detrects character development.
To me, Cath is more about her being fun, and less about her sexuality, that is just one aspect, that you seem focused on, just because part of her quest line, is getting you into a threesome. She is supposed to be your 'fuck buddy', emphasis on 'buddy'.
Not to mention, it beats the fuck out of her being all jealous about you being with other girls, in fact, she wants to hear all about it.
