Everything you just said is my main playstyle.
I don't kill/rape/beat anyone, I don't use any sex related jobs, or any jobs, really, except Public Entertainer. The only time others touch my slaves is when I use the Interaction>Sex option for a 4some to get some Mana if I feel I need it. I so use the lab, but only for the battle slaves so I can win the last fight of the game, which, even with maxed slaves and good equipment, is quite tough. I pretty much never use the Farm, and I only attack thugs/bandits. I also never buy quild slaves. It's usually easier to buy rope and grab one from the wild.
All in all, you're just like me xP
