I wasn't saying that they were similar questions, just that one reminded me of the other. (Though I can see why one would think that.)

I'd say the answer to this is pretty simple. Laura ABF (if I remember the handle correctly) suggested of the original Torture vs. Specks dilemma that the avoided specks be replaced with 3^^^3 people having really great sex - which didn't change the answer for me, of course. This provides a similar template for the current problem: Figure out how many victims you would dustspeck in exchange for two beneficiaries having a high-quality sexual encounter, then figure out how many dustspecks correspond to a month of torture, then divide the second number by the first.
