When the dead rise, they will neither marry nor be given in marriage; they will be like the angels in heaven."
This suggests that somehowy we are to be transformed like caterpillars into butterflies.
Maybe not. Butterflies mate; caterpillars do not. I can't figure out what Jesus meant. I can't figure human beings resurrected as celibate eunuchs. And especially those that were castrated. Jesus resurrected Lazarus to the earth referring to himself as the resurrection and life and the context and references made to in that event had to do with a resurrection to human life ( "Lord I know he will rise on the last day." ) There is evidence in the Bible of resurrections to human life -and that of Jesus to life as a spirit, so both forms are doable. It is only a guess what Jesus meant unless the meaning was communicate by God. --One does not know for sure otherwise if resurrected humans will be able to marry and enjoy sexual relations, but sex and marriage is part of being human and I just can't see it any other way.
