What's the rule, generally speaking?

How can I properly prepare my own domicile for inviting girls over for 1NS's?

What about as FWB's, possibly even just to "hang out," regularly?

What legal protections should I look into?

What protective / precautionary habits should I get into?

What if the girl is a stripper or an escort?

What if she has a boyfriend / husband?

Perhaps most importantly: what if it is lavish, flashy, fancy, or otherwise upscale?

My gut tells me "don't ever let women know where you live," but my place is in a pretty good location (about 6 minutes from downtown), and I could see it becoming a party pad. I might want to make those 2 attractive features work to my advantage and get lots-o-laid but I don't want to get screwed.
