Will we still have sex after our death?

It depends on which religion you follow.

Mainstream Christianity (Orthodox, Catholic and Protestant) do not believe in sex after death, in accordance with ark 12:25 "For when they shall rise from the dead, they neither marry, nor are given in marriage; but are as the angels which are in heaven." It is incorrect to say that we do not have bodies: we do have resurrected bodies, but they are "spiritual" bodies (ie not made of matter as we know it).

Muslims DO teach there is sex after death. There is the famous promise of the hadiths:

"Abu Umama narrated: "The Messenger of God said, 'Everyone that God admits into paradise will be married to 72 wives; two of them are houris and seventy of his inheritance of the [female] dwellers of hell. All of them will have libidinous sex organs and he will have an ever-erect penis.' "

Sunan Ibn Majah, Zuhd (Book of Abstinence) 39"

Hindus, Jains, Buddhists, Sikhs, Druze, Rosicrucians, Scientologists, Wiccans and many other religions all believe in Reincarnation, so in these beliefs there is a possibility of reincarnation as a sexual being.

Mormons believe that their members can have a celestial marriage which survives death, so presumably they will still be man and wife and still have sex after death.

Raelians believe in an afterlife based on aliens re-creating the original person, and believe that these recreated people are capable of having sex.

Pantheists (eg Christian Scientists) believe that at death they merge with God, and so sex is impossible.

Atheists believe personal existence ends with death, so there will be no sex.

No one lives in any form after death. Even Lord Krishna is wrong. It is true that there are spirits but spirits are separate elements and their lives are different. A human being is not a single spirit. The soul is just an energy which needed for the functionality of a body. This energy remains in a body until the body is in a good condition. This energy is not a spirit. It has no image and it doesn't live separately after death of a person.

A human being is just a robot made of flesh, bones, tissues etc., and a toy of many spirits for their games.

Absolutely no.

The Bible has had it right for millenniums. A live dog is better off than a dead lion.

For the living are conscious that they will die; but as for the dead, they are conscious of nothing at all, neither do they anymore have wages, because the remembrance of them has been forgotten.” Ecclesiastes 9:4, 5

A short walk around any ancient graveyard will soon confirm that truth.

According to God’s Word, therefore, while people are alive, they are aware of death. When death occurs, however, they are aware of nothing.

They do not stand beside their own corpse, observing what is done to it. In nonexistence there is neither pleasure nor pain, neither joy nor sorrow.

Those dead are not aware of the passing of time. Theirs is an unconscious state deeper than any sleep.

Sometime in the future, if they are in God's memory they will be resurrected.

Umm... if we consider the state of the dead the answer becomes quite obvious.

"After Solomon observed that the living know that they will die, he wrote: “But the dead know nothing at all.” He then enlarged on that basic truth by saying that the dead can neither love nor hate and that “there is no work nor planning nor knowledge nor wisdom in the Grave.” (Read Ecclesiastes 9:5, 6, 10.) Similarly, Psalm 146:4 says that when a man dies, “his thoughts perish.” We are mortal and do not survive the death of our body. The life we enjoy is like the flame of a candle. When the flame is put out, it does not go anywhere. It is simply gone.

Jesus Christ spoke about the condition of the dead. He did so with regard to Lazarus, a man whom he knew well and who had died. Jesus told his disciples: “Lazarus our friend has fallen asleep.” The disciples thought that Jesus meant that Lazarus was resting in sleep, recovering from an illness. They were wrong. Jesus explained: “Lazarus has died.” (Read John 11:11-14.) Notice that Jesus compared death to sleep. Lazarus was neither in heaven nor in a burning hell. He was not meeting angels or ancestors. Lazarus was not being reborn as another human. He was at rest in death, as though in a deep sleep without dreams. Other scriptures also compare death to sleep. For example, when the disciple Stephen was stoned to death, the Bible says that he “fell asleep.” (Acts 7:60) Similarly, the apostle Paul wrote about some in his day who had “fallen asleep in death.”—1 Corinthians 15:6."

At the resurrection we will neither marry or are given in marriage.

The same day came to him the Sadducees, which say that there is no resurrection, and asked him,

Saying, Master, Moses said, If a man die, having no children, his brother shall marry his wife, and raise up seed unto his brother.

Now there were with us seven brethren: and the first, when he had married a wife, deceased, and, having no issue, left his wife unto his brother:

Likewise the second also, and the third, unto the seventh.

And last of all the woman died also.

Therefore in the resurrection whose wife shall she be of the seven? for they all had her.

Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God.

For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven.

That would be nice! But I don't think so.

I don't believe in an afterlife at all. But someone asked Jesus (and he should know!) if a woman is married to a man, and he dies, and she marries another man, which is her husband in heaven? Jesus said there would be no marriage or 'marital relations' in Heaven.

Ecclesiastes 9:5

You have been misinformed .. The people of God get a new spiritual body,

with no more aches and pains .. no bad backs or diseases. Imagine that!!

We won't need sex in heaven ... ( whaaaat ? )

But every good thing here will be replaced with something better !

The original thought in our Creators creating was to have an Earth filled with perfect fleshly people

Satan has no power to stop that and neither mislead and continuing to mislead so called christians

Christ replacing Adam would have meant nothing

No. The bible states -

For the living know that they will die; But the dead know nothing, And they have no more reward, For the memory of them is forgotten. Also their love, their hatred, and their envy have now perished; Nevermore will they have a share In anything done under the sun.

(Ecclesiastes 9:5-6 NKJV)
