I'm not a man hating lesbian, I like men just not sexually but the idea that they can "convert" or "fix" us, cured by cock if you will, is just something that's a bit too close to home and really frustrating. It's not all men that's why i'm not a man hating one and some of them say it as a joke when it's been brought up but there are those that do think it.
I've said this before, but it's worth repeating to get my perspective on the issue: There is no situation in this game in which you will be able to "cure a lesbian by cock." I find that concept insulting myself. Callie is not sexually attracted to the MC, and no matter how much manipulation and begging he does, this won't change. She might be willing to let him have some fun because she cares about him, but she won't become attracted to him or let him actually have sex with her.
The only way to get around this will be by using magic to change her sexuality. He's not going to "cure" her, and he's not going to remove her existing preferences. In other words, you won't make her straight, but you will at some point be able to make her bi through specially designed magic. Importantly for this discussion, it's entirely optional, at least when it comes to Callie.
Unless porn is meant to be completely vanilla (which is fine but quickly grows dull, in my opinion), there's always going to be something taboo about it. It might be infidelity, incest, public sex, anal (which is hardly taboo anymore, but I digress), or any number of other things that break some societal norm or another. I recognize this and have built a game that plays with taboos and the breaking of some of them. This will always cause offense to
someone, but I try to do things as respectfully as the genre allows me to. Among other things, that means that I take Callie seriously as a character with her own challenges, desires, insecurities, and limits.
I have deep respect for the LBQT community and their challenges, and the last thing I want to do is to offend anyone. But when taboos are involved, this becomes impossible to avoid entirely. At least I hope that the optional nature of most of these taboos means that those who dislike them won't feel like they're being forced into them. Take the sleep molestation, for example. You should be able to get through the game, and get the best ending, without engaging in that content after the brief tutorial during day 1. The same will be true with Callie.
