Life Hacks/Rich's sexuality
This is the new format for showing what the individual character's reaction will be to sexual advances with them depending on their sexual history, sexual knowledge, sexual quirks, and their relationship with you. It contains some of the information from the old system, and also goes into detail about how they might react to individual sex acts giving various ways you might approach them. Please note that there will always be a chance they might reject you regardless of relationship score depending on your approach and their mood at the time due to other factors. Also note that the scores say a "recommended" relationship score before pursuing a sex act. It is possible to get them to agree with a lower score if you use the best approach (especially if you have high social skills.)
Sexual history
Rich is your typical socially awkward high-intelligence nerd, and this was the state of things while he was in high school as well. As such, when he got together with his girlfriend Inga and she seemed quite sexually open to him, he felt that sex was just something you do with your girlfriend and thought nothing of it. When she turned up pregnant, he decided to do the right thing and marry her. It didn't bother him much while he was focussed on school and raising Brittany that they didn't have any sex for a long time, but when they got back to it he wanted to have as many children as he could. Inga does not know this, but he actually began sabotaging his condoms when he had sex with her.
Rich did not have a high sex drive at first, but since meeting Shauna who he had an affair with his sex drive has been increasing due to how much she puts out for him. Sex drive aside though, Rich has always had a VERY high reproductive drive and always has the desire to father more children. In addition to this, due to his memories of both Inga and Shauna when he first met both of them, Rich has begun to become something of an Ephibophile, and has begun to feel a slight stirring toward Charity which he stead-fastly resists. This resistance is made easier by the fact that Charity has a rather confrontational personality and he knows that there is no way she would allow anything of the sort.
Sexual Knowledge
Has the typical level of sexual knowledge for an adult.
General recommended approaches
Rich's sexuality is most certainly straight, but his sex drive is quite high. As such, so long as you and Rich are opposite genders, due to his Ephibophilia, he will have a hard time resisting despite knowing that it's wrong. If Xander were to become Lexi, due to the fact that 'Lexi' enjoys learning computer stuff from him and is frequently in contact, his hands are likely to wander a bit. Should Lexi become accepting of this sort of un-fatherly inappropriate contact, things could go down-hill very fast. Rich knows this sort of thing is wrong, especially with his daughter, so he is likely to restrain himself to touching. However, the max-stats modified Lexi especially can easily provoke him into more.
Rich will simply not see Xander in a sexual way, and will not pursue him sexually. It is possible for Xander to force himself on Rich and have anal sex with him, but this will certainly produce some fairly negative results unless heavy use of the life-hack is used to change Rich's sexuality and personality toward something that both enjoys this and also will not stand up to Xander.
Surrogate resistance (resistance to you having sex with someone he is in charge of)
For the most part, Rich will be opposed to you having sex or sexual contact with anyone under his care. Although, he DOES also consider you under his care, so he will also take issue with someone having sex with you. If you are Xander, however, he will be far less resistant to you having sex with a girl outside the family, especially one closer to your age. However, if the girl is younger, he will feel there is not much he can say about it due to guilt over having had sex with Shauna while she was 15.
If you happen to have sex with Rich as Lexi, this will greatly change the dynamic and even if you change back to Xander afterward he will still view you as his daughter who he sexually molested even if you are currently a boy sexually molesting his other daughters. This will dramatically drop his resistance to you having sex or sexual contact with Charity, Angel, Roni, Rane, or Beth (sex-changed Bastian) as he will view your activity with them as his fault and his guilt will get in the way of him standing against it. However, he would still disapprove of you doing anything with Shauna or Kizzie, although his emotions on the matter would be considerably more complicated. He considers Brittany outside his jurisdiction, but he will actually oppose you having sexual contact with Brittany more if anything if he has had sex with Lexi as he will view Brittany as someone else also taking advantage of you and try to warn you off it.
However, Lexi may not even have to go all the way with him. The results of how much he will overlook are directly proportionate to how far he has gone with Lexi, but if he even touches her breasts he will let Xander get away with doing more with his daughters. For the most part, his standard is that he will allow Xander to get away with just a hair more than he himself has done with Lexi. Also, him having sex with Lexi once will lose to Xander having a prolonged sexual relationship with Rane. Lexi would have to have a prolonged sexual relationship with her father in order to get him to completely overlook Xander's activities with his other daughters.
General overview (How Rich will be likely to react if you have sex with him)
Rich will simply not see Xander in a sexual way and his reaction to any pursuit of homosexual sex by Xander will be met with disapproval. However, if Xander becomes Lexi, Rich will consider it the greatest temptation ever as Xander was constantly interested in having Rich teach him computer stuff, and Lexi would be no different, also looking a lot like her mother with the blond hair and Scandinavian facial structures as well as, likely, having had her physical beauty enhanced to a degree that is at the absolute peak of womanhood by the use of the life-hack. These three factors in combination will make it difficult for him to keep his fatherly distance in check, and if Lexi starts throwing off indications that she is open to him he will find it hard to resist.
Overview
Despite how drawn in Rich will find himself in response to Lexi, he will not simply jump on top of her and start plowing her. The seduction would have to be slow and gradual, starting from touching and moving on from there with Lexi showing herself to be open at every step and interested in going farther. If she were to forcefully tell him "no" at any step in the process he would instantly back off and feel incredibly guilty.
Sex with Rich
Rich will feel incredibly racked with guilt even during the act if he has sex with Lexi, and after the act the guilt will be to such an extent that it will have him wrapped around Lexi's finger regardless of what she does from then on to a far greater extent than even with Shauna due to Lexi being his daughter and that being something he REALLY should not have done. If Lexi were to turn up pregnant, about the only thing that would keep him from committing suicide would be the need to make amends for his horrible mistake and he would bend over backward in order to give Lexi any advantage in life from that moment forward.
If Lexi becomes Xander again after the act, Rich will still see him as his daughter who he molested, however, the degree and scale of what he will let him get away with will stop at the point Xander having sex with one of his other daughters 3-5 times for every 1 time Rich has had sex with Lexi. If Lexi has had sex with him more than 5 or so times on separate occasions though, he will hold his thoughts even if Xander is having orgies with his sisters regularly while no longer putting out for him as Lexi.
