Hmm, it does depend if you put value on that, which I assume most people do, this is the two things which everyone obsesses about idea, like Freud's Eros and Thanatos.
Would the plus of information you want, if sex doesnt matter substitute something else, be worth it if you were also made conscious of something you did not want to know, if death doesnt matter substitute something else.
So you are in fact asking an existential question about attitude to life...I didn't grasp this at all from the previous framework.
I think you're asking something like:
Enjoyable activity A is finite in number; does the particular knowledge that it *is* finite *and* the further knowledge that it will lead to unpleasant activity B at the last occurrence, mitigate your pleasure in activity A. And I add to that the assumption that both A and B are in some sense inescapable activities of a lifetime...by which I mean that avoiding A completely would not mitigate B...
Have I got the question right?
My answer to that particular conundrum is that given that B is inescapable by any method, I am not at all concerned that A provides a countdown method to it. Especially since as I already commented, no knowledge of the *rate* of occurrence of A is available. (By contrast - if I knew that A happened once a year, and that there were fifteen As before death B, then I could usefully employ an accountant to plan my finances so I exactly ran out of money in fifteen years time...)
About death and also about repeated experiences in life...I don't think any two experiences are ever the same, not really. I might celebrate my birthday every year, but each year the people and the place are a year different from before. In that way *every* occurrence of A is special and to be enjoyed in the moment, and also every occurrence of A is a small death, a small letting go, a small falling into the totality of momentary Joy, never actually repeatable and thus exquisitely treasurable and uniquely irretrievable afterwards...both fully alive to every moment and fully non-regretful of the past which has been eternally released...
I think that's how I hope to feel about my life...being in the essential flow of eternal life encapsulated in death, or vice versa, depending on how you prefer to describe it. Life in death, or death of life so life might spring clear from it... I hope that is an existentially framed answer which answers what seemed to me to have become an existential question.
Tl;dr I'd enjoy every moment of the sex, without limit and without foreshadowing, treasuring each time as special and each partner as unique and rare and precious. I'd drop the counting machine behind the bed and not make any notches on my bedpost either.
