Boy, do I love your honey words :D
So if I understand correctly:
RL4 - Things like stripping naked, doing tasks nude, etc.
RL6 - What services do you mean ? Like blowjobs etc. ?
Because for me personally my favorite heroine archetype is prude being forced into embarassing situations, where she's ashamed and passive. But inside she hates every second of it. And ideally without sex, but with lots of groping and teasing.
