Somebody posted a few months back trying to find an erotic European film
from the 70s set in a convent.  The following description of a Jess (aka
Jesus) Franco film is from the Trash Palace website.  LT
*Love Letters Of A Portuguese Nun (1977)-SWITZERLAND / GERMANY-After being
sent to a convent, Maria, a young virgin (Susan Hemmingway) discovers that
it's run by devil-worshipers! Similar  to, although not as insane as
"Justine", but a good deal raunchier! ADULTS ONLY
