This works for me. A little tweaking here and there, but this works. Thanks.
These prices for a sex worker by means of that formula seem problematically underpriced, within the context of the fictitious D&D "economy".
Im not sure how much a reallife sexworker charges for an hour or a night. I assume it varies regionally.
But suppose the cost is $500 per hour for a visit.
A reallife hand-forged weapon-worthy sword costs roughly $400. So, the price of a sexworker might be the price of one or two swords per hour.
So, in the D&D "economy", a sword costs 15 gp.
So, in the D&D "economy", a visit by a sex worker would cost say 15 to 30 gp.
Adjust this number accordingly if one happens to know the reallife cost.
In college, two friends are sex workers, but I never discussed the business transactions with them. One is an anthropologist whose thesis was about exotic nightclubs as a microcosm of Western gender constructs. Heh, she analyzed her customers as an exotic dancer at a nightclub. Also on a few occasions, she chose to work as a high class sex worker, such as on a yacht, to understand the dynamics. Her paper turned out brilliant and changed the way I think about sex work. Her main point is, the places that have the most liberal laws with regard to pornography and prostitution, also have the highest status of women, including personal autonomy. The places with the most criminalization and censorship, also have the lowest status of women, including the least personal autonomy. There is a direct correlation between society controlling images of women and controlling the actual living women. In other words: pornography = human rights. The reality is the opposite of what some religionists or feminists might claim.
