I haven't seen any of the Lifepath stuff yet, other than the public posts on Patreon, but I have long thought that a pretty high level of promiscuity really needs to be a requirement to even accept the job, at least as it's currently defined. I mean, if they just were pitching that she had to be a stripper, it's believable, but an actual prostitute is a bit much unless she already has an extremely casual attitude about sex.
So, when I was in college, I went through a phase where I thought it would be really cool to be a spy. And nooooo Sydney Bristow had absolutely nothing to do with that... So anyway, one of the things I pondered was, if I was a covert operative, could I sleep with someone as part of the job. I decided that I probably could if it was really important. If I got the pitch they give in the game, however, I'd nope the heck right out of that room.
It's probably way too late in the process to change, but I really do think it would work better from a narrative standpoint if the job were pitched as working at a strip club, and she'd have to seduce the target. So they tell her upfront that it's common for the strippers to have sex with the customers, but she only has to sleep with the ultimate target. Maybe when she gets there, however, sleeping with the clientele is more "encouraged" than she was led to believe. It could either be bad intel, or otherwise she was deliberately misled when given the mission. We already know (or at least suspect) that the psychiatrist is a bit shady.
So then this ties in with the whole corruption theme. Just how far is she willing to go? The more she declines to sleep with patrons, the greater her suspicion rises. Sleeping with patrons, however, increases corruption and stress. Being promiscuous in the Lifepath section, however, lowers (or maybe at high enough levels eliminates) the stress increase.
