Even Paul said that we don't know exactly what we will be like, but he did say we will have a body. And he said we will be like Jesus in body.
Post-resurrection, Jesus assured his disciples that he had a body and wasn't merely a ghost/spirit. He ate with them to prove it. He still wore his scars and had Thomas put his hand in the wound. (That post-resurrection body was/is a MAJOR bit of Christian theology.)
He deifintely had a body.
But that body passed through locked doors. It appeared and vanished. It was a physical body with different properties than our current forms, which would also match what Paul taught in 1 Corinthians, that we would receive a new body with additional properties, as well as the deletion of some (mortality/death/sin nature).
So, we don't know exactly what it will be like, but I believe there is good argument that we will not be disembodied spirits.
But Jesus also said that in heaven, per "marriage", we will be like the angels and "not given in marriage". I take that to mean that there will no longer be a need for procreation, no need for sex, and we may not have genitalia.
But that is much assumption.
