as for the playersexual thing, yeah, it would definitely not hurt to have a baseline preference from the followers and them requiring a bit more "work" in order to convince them to see us as a romance target, with potentially an initial rejection and then the character coming back after some time passed...
I don't think that an initial rejection based on sexuality followed by a later acceptance would be a good implementation. That would seem to imply that sexuality is a choice and you can make someone be attracted to you by perseverance even if you're the "wrong" gender for their sexuality.
An initial caution - "I've never been in a relationship with a man so let's take it slow okay?" - is fine, but an outright "I'm not attracted to men" [time passes] "okay now I'm attracted to men" is...not great.
