Sort things out with his girlfriend.

Underneath the "Sexual" tab, there are two subsections, "Habits" and "Philias." "Philias" could be interesting to look at later, but you start with "Habits." Here you notice a rule that makes you feel a little guilty:

When with a sexual partner, has sex with them once per week on average.

The rule reminds you that it's not just Jack's life you're changing, but his girlfriend's too. You don't want her to be heartbroken, do you? So you take a quick detour to the "Society" tab of the app, the set of rules that governs how a person is perceived by others. Here you add a rule to make his poor girlfriend's life a little easier, and another to make his own life easier:

Women always perceive him as straight.

Men quietly accept his sexual orientation and do not treat him with homophobia.

Finally, returning to the "Sexual Habits" section, you add one more:

Likes having a girlfriend and will happily agree to any sexual proposal his girlfriend makes, not because he gets sexual or romantic pleasure out of it, but because he loves making his galpals as happy as possible.

There, you think. Jack still gets to be a chick magnet, his girlfriend stays content, but in reality he'll be a committed gay from here on out.
