Sodomy is natural.
For this cause God delivered them up to shameful affections. For their women have changed the natural use into that use which is against nature
.  And, in like manner, the men also, leaving the natural
use of the women, have burned in their lusts one towards another, men with men working that which is filthy, and receiving in themselves the recompense which was due to their error. ~ Romans 1: 26-27
Smallpox is natural. Leprosy is natural. These diseases are natural, but they aren't healthy.
Diseases are natural but they're ABNORMAL, hence they go AGAINST the NATURAL ORDER.
Faggotry is also abnormal and goes against the Lord's natural order.
