That is the matter of proper understanding of the Old Testament Law. It consists of three parts:
1. Perfect moral Law of God which is unchangeable
2. Ceremonial Mosaic Law (burnt sacrifices, circuмcision etc.)
3. Civil law governing the daily life of Israel
The first one is of course in force, the two latter ones were abrogated by the coming of Christ, as they were only part of the Old Covenant.
Thus, for example, condemnation of ɧoɱosɛҳųαƖity, bestiality, incest etc. in Leviticus 18 and 20 falls into category 1. When Our Lord taught to love our neighbor as ourselves, he was quoting from Leviticus 19:18, becaue this is part of the perfect moral law of God.
On the other hand, prohibition of wearing clothes from two materials, eating shellfish etc. belong to category 3 and are not binding on Christians.
And since "Jesus never condemned ɧoɱosɛҳųαƖity!" then that's even more proof that ɧoɱosɛҳųαƖity isn't wrong.
Jesus defined marriage in Matthew 19 in a way which absolutely excludes ɧoɱosɛҳųαƖ unions, not to mention explicit condemnation of sodomy by St. Paul (1 Corinthians 6:9-11, Romans 1:26-27).
