Well, LB, don't base your impressions on what "pagan gatherings" must be like upon my interest in Biblical Historical Criticism.
Most pagans probably don't give 2 shits about Biblical Historical Criticism... They are much more likely to be honoring Gaia and the Green Man and other such dieties at their rites. Playing drums around a fire, things like that.
I think it's fine you want to love, to be poly, to have gay sex, and still ID as a Christian. I see who wrote the Bible, when, why and so on has nothing to do with the bits of Jesus' philosophy you agree with. Hey, whatever gets you through the night!
You might want to look into gnostic Christianity. It was the first Christianity, it was the most popular Christianity of the first few centuries, before Constantine forced the bishops to agree on what was "true canon," and what was "heresy" in the documents floating around the area back then.
Much of what Paul wrote is gnostic. After all, if Christ is in you (and me) as I above quoted, there is no need for church, paid priests, fancy buildings, forced tithing, paying for masses for departed souls, etc etc. All you need is a few people coming together to pray, sing and share the Eucharist.
I prefer gnosticism over orthodox Christianity myself. In it, Mary Magdalene has a bigger role and her own Gospel. Even Judas is given a break, and his own gospel. The angry god of the Old Testament (Yahweh), is called the Demiurge or Ialdabaoth, and is considered a lesser god, not the Father of whom Jesus talks with such love.

I own a book called The Other Bible which contains many gnostic gospels and acts, as well as writings from the mystical Judaism called Kaballah. I find gnosticism to be quite similar to Buddhism since it is more interested in personal enlightenment, and not dependent on priests and bishops to be involved in forgiveness of sins. It is also more woman friendly and has a concept of Sophia, or Wisdom. She was present in the Garden of Eden. She was brought to earth in the bodies of the 2 Marys, Virgin and Magdalene. (The feminine divinities present at the Christ's birth and death, womb and tomb.)
Gnosticism is much more democratic and therefore was a threat to the Roman Empire and banned.
I never understood why Jesus had a Father and no Mother. It was revealed to me through gnosticism that the Holy Spirit is Sophia, and Jesus' Mother. The dove that flew down at His Baptism, who said, "This is my son, with whom I am well pleased"? The dove was a common GODDESS symbol of the day. This dove was Jesus' mother, and also his consort, the Great Mother, Sophia.
I like balance in my life and in my creed. Therefore, I prefer the way gnosticism balanced the masculine and feminine, the Father, the Mother, the Son, the consort of the Son, who came to aid him in his mission on earth. Mary Magdalene anointed Jesus' head and feet in preparation for his arrest, trial, crucifixion and burial. She "got" him, while the male disciples were thick and blundering. "Magdalene" is a Greek form of the Hebrew word "tower," migdal, as in Tower of Faith.
Once I realized all this, Christianity made sense to me in a way it never did before. I believe the "beloved disciple" in the canonical Gospel of John was Mary M, not St John. I feel Leonardo da Vinci realized this when he painted a feminine figure leaning on Jesus' shoulder in his Last Supper.
