Some brothel customers request whores to strip instead of having sex with them. I'm not sure if it's intended, but if it is a button to disable it in the brothel setup menu would be welcome.
Stripping is intended to be a fallback if all others are banned.
When it is occurring too often it is a bug.
I am changing the way customers choose their preferred sex type so it will accommodate banned sex types better.
There is still a bug somewhere in the sex choice code I have not found yet.
When I fix it, stripping will be rare as a sex choice unless all other types are banned.
As for the other jobs having secondary side effects of the girls being too horny and having sex with the customers,
If a sex type is banned she will try one that is not banned,
If there are no banned types that will satisfy her, her obedience or some other stat is not good or her libido is very high,
She will break the rules.
