The important point is that you cannot get much more Protestant Christian than the Presbyterian Church.
Presbyterian USA is known as apostate among us conservative Christians. When I was a new Christian I joined the local PCUSA and within a year recognized their false (unbiblical) teachings. I made some good friends there nevertheless and eventually all of us found our way to orthodox churches.
There are at least two conservative Presbyterian churches that I know of, that I understand to be orthodox: Covenant Presbyterian and Orthodox Presbyterian. There aren't any in my vicinity or I'd certainly check them out. As conservative assemblies they would hold to what the Bible says about marriage and about homosexuality.
