It comes down to what love is, and what marriaqe is, and what sex is.
I have unconditional love for a lot of people that I will never sleep with. Part of my love for them is that I would not even TRY to sleep with them. Maybe the purest form of love is one that isn’t lookinq for sexual pleasure from the other person - when there’s nothinq in it for us except the joy of valuinq and nourishinq the other person. Like the love of a parent for a misbehavinq child.
Does unconditional love end? Why stop havinq sex with somebody if the unconditional love which prompted the sex never ends? If a person marries one person do they stop havinq unconditional love for everybody else because they’re not havinq sex with them any more? Or should married people be sleepinq with everybody they love unconditionally?
If the questions are to me, the logical answer would be applied set theory.
Love intersects marriage, which intersects sex, which intersects love.
Logically, all else being equal, no given attribute automagically need imply inclusivity or exclusivity from any given set.
I know... math, ugh... most people don’t have a clue... but math (and not the bible or the koran or kama sutra etc) is the universal language of intelligence and reason.
make math, not war
