You need to get some reading glasses as the scripture does not speak of sex - though you wish it did
You should look at it more closely.
Romans 1: (20-32)
19 Because that which may be known of God is manifest in
them(Those at the creation of the world.); for God hath shewed it unto
them(Those at the creation of the world.).
20 For the invisible things of
him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that
they (Those at the creation of the world.) are without excuse:
21 Because that, when
they (Those at the creation of the world.) knew God,
they(Those at the creation of the world.) glorified him not as God, neither were thankful; but became vain in
their (Those at the creation of the world.) imaginations, and
their (Those at the creation of the world.) foolish heart was darkened.
22 Professing themselves to be wise,
they (Those at the creation of the world.) became fools,
23 And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.
24 Wherefore God also gave
them (Those at the creation of the world.) up to uncleanness through the lusts of
their(Those at the creation of the world.) own hearts, to dishonour
their(Those at the creation of the world.) own bodies between themselves:
25 Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
26 For this cause God gave
them (Those at the creation of the world.) up unto vile affections: for even
their(Those at the creation of the world.) women did change the natural use into that which is against nature:
27 And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of
their (Those at the creation of the world.) error which was meet.
28 And even as
they (Those at the creation of the world.) did not like to retain God in their knowledge, God gave
them(Those at the creation of the world.) over to a reprobate mind, to do those things which are not convenient;
29 Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers,
30 Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents,
31 Without understanding, covenantbreakers, without natural affection, implacable, unmerciful:
32 Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them.
