Homosexuals have existed for a long time, some, not having told others they were like that, remained unknown. They are just like heterosexuals, they can produce children if they are an intersex, with their other partner, or they can have a friend impregnate them. They can also adopt children. I myself, am homosexual, and I know that some of us choose not to admit it to others. So its very likely that back in the Bible times homosexuals existed, but just never mentioned it, or just married to the oposite gender because it was expected. You can be a Christian and still be a homosexual, even though God doesn't really adress the issue, its believed to be a heavily punishable sin and people like this are shunned. People need to realize that they are all the same, we all (most) have bodily functions. We all sin, lying is a sin, so is putting other things before God (phones, music..) and all sin is equal, so therefore we are all equals. We will be forgiven for our sins.
