He never specifically mentioned a lot of things: child abuse, rape, necrophilia, bestiality, etc... He did say that He came not to abolish but to fulfil the law. And he extended the law to include intentions of the heart. So if anything, he would extend the sin of homosexuality to include homosexual lust. There's no possible way an honest person can claim he took no position on the matter.
And he did define marriage very clearly as being between a man and a woman.

Actually did mention beastiality:
Ex 22:19 Whosoever lieth with a beast shall surely be put to death.
Leviticus 18:23
Neither shalt thou lie with any beast to defile thyself therewith: neither shall any woman stand before a beast to lie down thereto: it is confusion.
Leviticus 20:15
And if a man lie with a beast, he shall surely be put to death: and ye shall slay the beast.
Deuteronomy 27:21
Cursed be he that lieth with any manner of beast. And all the people shall say, Amen
RAPE:
25But if a man find a betrothed damsel in the field, and the man force her, and lie with her: then the man only that lay with her shall die.
26But unto the damsel thou shalt do nothing; there is in the damsel no sin worthy of death: for as when a man riseth against his neighbour, and slayeth him, even so is this matter:
27For he found her in the field, and the betrothed damsel cried, and there was none to save her.
