Handjob, Titjob, Footjob and Vaginal Sex are what you'll have to avoid, maintain high enough cock desire so ppl dont come on the floor. (you'll get a sadism level around 20 I think and some more after that)How do you avoid getting sadism passives? is it even possible?
Never let your cockiness reach 100% and don't subdue prisoners using attack skills.
It's not impossible but it's certainly not easy - don't bother unless you are trying to get the masochism passives I'd say.
Nerds will initiate Footjob simply based on Cock desire and normal Prisoners will do Handjobs the same way, you'll need the 2 ring edicts to raise the desire needed for either I'm pretty sure or you will eventually pick up a sadist level from there.
