Hello Blanche,
First of all, Jesus did in fact speak regarding this sin in referring to sexual immorality, which means of every type. And secondly, the word of God states that "All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the servant of God may be thoroughly equipped for every good work." This means that the prophets and the apostles where writing and speaking through the Holy Spirit, which means that God is the author of His word. So yes, Jesus did speak about homosexuality. Here are a couple of examples:
"For this reason God gave them over to dishonorable passions. Even their women exchanged natural relations for unnatural ones. Likewise, the men abandoned natural relations with women and burned with lust for one another. Men committed indecent acts with other men, and received in themselves the due penalty for their error."
"Although they know God’s righteous decree that those who do such things are worthy of death, they not only continue to do these things, but also approve of those who practice them." - Rom.1:26-27, 32
"In like manner, Sodom and Gomorrah and the cities around them, who indulged in sexual immorality and pursued strange flesh, are on display as an example of those who sustain the punishment of eternal fire. " - Jude 7
These are just examples of scriptures which are God-breathed and there are many, many more regarding this subject.
