You have asked: Again, what version of the Bible do you use? This is actually irrelevant, but let's get it out of the way. I have a KJV, NKJV, NIV, ESV, NLT, etc... I prefer KJV, though. Now let's get relevant.
You stated: "Jesus created the New Testament with his followers which meant that the Old Testament was supersedeed by his teachings since "All Come to God through him". Interestingly Jesus never talked about Homosexuality at all." (The part about superseded is complete folly)
Jesus came to fulfill the Old Testament, which He did. So, if we are to follow Him, for He is the only Way, we accept everything about Him and what He fulfilled. He is that very Word, (The Old Testament) in the flesh, that He came to fulfill. He does not contradict Himself. And He did not need to talk about homosexuality, beastiality, sodomy, men trying to be women and vice versa, etc... again... He already did. The Old Testament is absolutely relevant, my friend. Very much so.
