Well Al R, then you'll like the: 'Twelve Month Unaccompanied Tour Tie'.
The motif of the tie comprised the roman numerals XII, beneath which was the female sex symbol of a circle with cross beneath. In the circle was the symbol for a 'No Entry' road sign.
The tie was generally not available until one was almost tour-ex.
One chap had the tie but it had a cigarette burn strategically in the 'No Entry' bit.
I suppose in these enlightened times, we would need to have two ties available to cover - how can I put this delicately - the more liberal interpretation of what constitutes sexual abstinence!
