What the bible says about homosexuality

Ok, I'm just going to say something. A friend and I got in a debate about homosexuality. Here's my stance which coincides with the Bible. It's a sin. I don't judge the people, I'm even friends with some. But I'm not going to call what God calls an abomination, good. Now some people may bring up that in the Old testament, God says eating shrimp is a sin. Well, unfortunately for those who would use that argument, I'm not just basing this solely off of the old testament. Mark 7:19: since it enters not his heart but his stomach, and is expelled?” (Thus he declared all foods clean.)
.

The NT clearly indicates that the food laws are null and void. However, the NT also CONFIRMS that homosexuality is a sin, in Romans and in 1 Corinthians.
Also Mark 10:6-9: But from the beginning of creation, ‘God made them male and female.’ ‘Therefore a man shall leave his father and mother and hold fast to his wife, and the two shall become one flesh.’ So they are no longer two but one flesh. What therefore God has joined together, let not man separate.”

Notice it says "male and female" not man and man or female and female.
