There is currently no limit to the number of times you can have social interaction with a slave in a day (unlike sexual interaction which is limited to 1/day/slave). Not sure if it's intended or a bug ? As it is, that means it is possible to make slaves go from "just captured, hates you" to "fond of you, agrees to unlock sex" in the same day by talking to them multiple times.
Also not sure if working as intended or not, if you end a social interaction with "request intimacy" and switch to sexual interaction, it will not count in the limit of sexual interactions you can do per day. (it will however count as the limit of 1/day for that slave). So for example with 3 social and 3 sexual available/day and enough slaves, you can in fact have 3 social and 6 sexual in total.
