Any advice on what I can do with this character? First run through so no idea of a plan of attack ....
Yes, that is a great approach to making money off of female captures. But I prefer to add those to the household first, so I can sell them at the slave market in Crystal Heights.
You don't want to sell her?
There are two problem traits I see, frigid and feminist. You can overcome frigid by getting her to like you (raise affection to loving), feminist by corrupting her (raise corruption above 50). Then frigid won't bother you anymore and feminist will work in your favor. Both of those will fuck away over time, frigid in particular.
How?
I wish I could give a straightforward answer to that question. But it actually depends very much on what your character is good at (charm, copulation, manipulation, flagellation, bondage...), the state of your house (everything renovated nicely?), and any nuber of other factors.
Raise affection!
Take her out to the theater and cuddle, to dinner and tell jokes, do all of the friendly talks (Are you okay? About me? Encourage, Compliment beauty...), share a bathtub (normal, not dominant, scrub her, talk to her). There's a lot of expertise to be found in this thread on how to raise affection. And of course the wiki. When my stats allow it, I just request vaginal sex dominantly until they like me. But at that point of character development, I am basically able to ignore the frigid trait anyway.
Corrupt her!
Put her on morning blowjob duty until she has some defiance (4 is probably more then enough) then you can have her go to the dungeon for her deserved punishment. There you need to get her to orgasm in bondage. My usual approach is whip or dildo until arousal is at 9, then let her to orgasm while deepthroating you and corruption goes up by 2. If something you do lowers arousal without an orgasm, backpedal! Don't continue doing something that turns her off. Again, this thread and the wiki have information you can use.
