How is homosexuality against God's design?
I have seen many of the verses explicitly stating homosexuality is a sin, and also have the belief and understanding that none of them are as clear cut as people lead you to believe. So please do not try answer with anything of the like, of course unless you have a unique perspective or they support another argument.
So my question is, how does homosexuality go against God's design? Where does the Bible make clear that marriage is only meant for between a man and a woman? And why would God do such a thing? Sensual attraction is not a choice, why would God make us feel this? Animals perform same sex relationships, so it's not unnatural. And finally who does it hurt?
The main question is how, where, and why does the Bible say sex and marriage is only for a man and a woman.
