I don’t know if you can strive for spiritual closeness or it just happens. But Jesus said there would be no marriage in Heaven. To me, that implies that there will be no sex but still loving relationships, maybe even more loving than on earth.
Agree.
“To me, that implies that there will be no sex”
Therein lies the difference between Christians (believe Heaven is a spiritual thing), whereas to muslimes, “heaven” to them is nothing BUT sex, pleasures of the flesh.
