edit : Radiant Prostitution Counts Clients in sexlabs diary.
tdf Prostitution does this too and both add their numbers (though i dont see a Need for tdf Player Prostitution wheen you use rp, i use tdf for follower) i wonder if it is possible to manipulate that number of Clients in sexlab diary, because i played half a game without it (but prostituted with another mod). I uncheck the restriction to Inn Keeper which allows me to work for any Innkeeper at any Inn as long as that offer of work chat line is in the chat menu of that Inn Keeper.
I haven't tried it, but that's how I understand it. If you leave that local while still in their employ you get a bounty placed against you. If you leave that local while still in their employ you get a bounty placed against you.
Uncheck that, and you can roam Skyrim, whoring for that same innkeeper, as far as I can tell.
in active mode you can prostitute road travellers like the bard, the wolf reviver, the cook, etc.
Switch back to passive or both mode when you are in a tavern and start your main Business.
Unfortunately the approaching does not work at groups like the alikir in swindlers nest, Sanguines guests in mistglove, etc, but you can take them active.
