who introduced sex to adam and eve.?

Question

the first man and the first woman on earth who taught them every thing about sex.

Answer 1

Genesis 1:28 says that God himself told Adam and Eve to “be fruitful and become many and fill the earth.” That would involve sexual relations between them, and God would have provided guidance in that regard for we find that concerning the first human pair: “they heard the voice of Jehovah God walking in the garden about the breezy part of the day.” (Gen. 3:8) During those periods of communication, the first man learned much that was for his benefit.

It should be noted that Eve ate first of the forbidden fruit and did so when she was by herself; only later did she give some to Adam. (Gen. 3:6)
The act of disobedience was not that of sex, but of failure to respect God's right to set boundries. By taking of the fruit of “the tree of the knowledge of good and bad,” Adam and Eve expressed their rebellion, not their awareness of sexual desire, for God had already given them the command to "be fruitful".

What the Bible forbids is not normal sexual relations between husband and wife but practices such as fornication, adultery, homosexuality, and bestiality. The bad fruitage of such practices shows that the prohibition is an evidence of loving concern on the part of the One who knows how we are made.

Answer 2

Before the fall Adam and Eve were not subject to their lower passions and had no inclination to have sex,after some time when they were ejected from Eden they must have discovered that they were now indeed subject to arousal and sexual feelings, and how to pro-create according to Gods command to them.
