Post-consummation reporting: Once the act is completed (typically after significant buildup of conversation and foreplay to ease nerves), the groom immediately separates from his wife due to laws of niddah (ritual impurity from menstrual-like bleeding, which begins here if the hymen breaks). He then calls his assigned rabbi or teacher right away—often from a phone in the kitchen—to report success. This confirms the mitzvah (commandment) of onah (marital relations, seen as a husband's duty) was fulfilled "properly," including that ejaculation occurred inside the wife (to avoid the grave sin of hotza'at zera l'vatalah, or "wasting seed"). The rabbi might ask brief questions like "Was there blood?" (indicating virginity and triggering the impurity period) or simply affirm "You did everything right."

Blood check: The couple often inspects towels or sheets for blood in the kitchen afterward (a holdover from biblical-era practices). If present, it validates the act; if not (common in ~40% of cases due to non-elastic hymens or prior activity), further rabbinic guidance follows, possibly including a medical exam. A follow-up call happens the next morning to ensure all is well.

This isn't universal across all ultra-Orthodox groups—variations exist by sect (e.g., Satmar vs. Lubavitch)—but it's a documented norm in stricter Hasidic enclaves like those in Brooklyn's Williamsburg.

Weber's essay vividly captures the awkwardness: Her groom, Moshe, "rushes out of the bedroom to call the Rabbi on the phone hanging on the kitchen wall," terrified of any misstep, while she lies bleeding and stunned, unaware this call was expected. Similar transcripts and memoirs (e.g., from artist Frieda Vizel, another ex-Hasidic woman) echo this, portraying it as both protective guidance and invasive oversight.
