Agnes Blannbekin (1244-1315) was an Austrian nun & mystic who had erotic visions. In one, she felt the foreskin of Jesus in her mouth. “And behold, soon she felt with the greatest sweetness on her tongue a little piece of skin alike the skin in an egg, which she swallowed.”

Edit! Agnes was not a nun, she was a mystic & a ‘Beguine’ - a movement of lay women devoted to god, chastity, poverty & the ideals of the vita apostolica. The beguine were often conflated with nuns but never officially recognised as such.

(I realise that isn’t the detail ppl are focusing on the most here, but we do want to get these things right.)

Just to clarify - In Agnès’ vision, the foreskin was not still attached to Christ. As a Jewish man, Christ was circumcised, but what happened to his foreskin afterwards was the subject of intense theological debate for centuries

Hope this helps.
