when you take her out in club you have to get her wasted and then said that you got condoms and fuck her raw afterwards
in afternoon after the chat on your way out you simply have to tell her you want her, tho if you want to knock her and fuck her raw, you must set her ovul day on next day (myself i usually change back middle scene on the day)
now this is sandbox (grind incl) shit takes time, if she just had child you have to visit her bout 5 times till you can have sex with her again, if you havent even reach this point yet , keep on doing all over till you get more options
no on both counts
