Yes, I read this information in several books. One of the best is a scholarly book by a Jewish historian, called The Hebrew Goddess. The author is very well-versed in Talmud, where the sages commented upon what was happening currently in Judaism, or had happened in the past. There is history written in the Talmud about the men's and women's courts, and what happened on certain holidays when the genders mingled.
Another good book on the subject is When God Was A Woman.
There is much information in the Bible (the Hebrew [Old] Testament) itself, about what we too often call "temple prostitutes." Sacred sex was common in all religions in the BCE period, in all the empires, Egypt, Babylon, Persia, Greece, Rome. It was not profane. It was a religious ritual. May 1, Beltane, was specifically celebrated by orgies in many cultures just to the north and east of Palestine. (Bel = Ba'al.) It was a spring fertility ritual. It was the goddess's wedding day. Humans often marry in June because, originally, May was the goddess's wedding and honeymoon, and so people would marry just after her month. (Mother's Day is near May 1 for a reason.)
In Exodus 32:6, when Moses went up the mountain to speak to Yahweh, and stayed away a long time, his tribe made a golden statue shaped like Yahweh as a young bull, and celebrated by eating and drinking then having an orgy. It is spoken of euphemistically. "They sat down to eat and drink and rose up to indulge in revelry." The Hebrew is clear on what this means.
Another good book about pre-historical sex and mating is Sex at Dawn. It describes past and current practices of stone age and bronze/iron age peoples. These ancient cultural practices linger on even in Europe to this day.
Thank you again for your thoughtful reply.
