Female students at Cambridge University have been ordered to curb late night noisy sex.
Undergraduates at women only Newnham College were warned in a misspelled email to be "discrete" because of the thin bedroom walls.
One classics student said: "I cringed. I thought it must refer to me." Another admitted: "Once I thought I was going to break the walls."
Junior Combination Room president Lizzy Cole said: "I sent the email after getting 10 complaints. But it seems to have worked."
