I would like to have, if possible, a clarification of two passages of the Mishneh Torah in apparent contradiction. In Sefer Nashim, Hilchot Ishut 3,11 Rambam expressly speaks of a lawful consecration through the biah method (sexual intercourse): «A girl [...] can be consecrated through sexual relations with her father's consent.». However in Sefer Nashim, Hilchot Ishut 10,1 it is said that according to rabbinic law a consecrated woman is forbidden to have sexual intercourse with her husband as long as she lives in the paternal house previa makkat mardut (beatings): «According to Rabbinic law, a woman who has been consecrated (i.e., an arusah) is forbidden to engage in sexual relations with her husband as long as she is living in her father’s home. A man who has relations with his arusah in his father-in-law’s home is punished with “stripes for rebelliousness”. Even when [the husband] consecrated [his arusah] by having sexual relations with her, he is forbidden to engage in sexual relations with her again until he brings her to his home, enters into privacy with her, and thus singles her out as his [wife].».
In the first passage quoted, does through sexual intercourse take place in the same house as the father? If so, in the second step mentioned, only a second sexual intercourse is therefore forbidden, but not the first? In fact I noticed “again” in Hebrew sheniyyah thus implying a previous sexual intercourse already occurred precisely with the “consecration” and which cannot be repeated before the nisuin. Is correct? Finally, would the beating be administered only with the second sexual intercourse to the exclusion of the first?
