Passed out from where Andre? Pirbright after Phase one or Larkhill after Phase 2?
At Larkhill you don't have the opposite sex in your rooms.
At your Regiment it is probably not advised unless you have a single man room, as your room buddies will all want to have a pop at your girl when you have finished - you will share everything after all! I think it is also not allowed, but I don't read Orders about Single Service accom as I dont live in it.
