Sex with a Bride before her wedding, Yes although this was with an ex on her hen night

here's a dare list
 

In a famous building, eg Buckingham Palace, the White House (public areas / rest room etc!)..

Have had a quickie at BBC studios, waiting to see a show.. left the bathroom, bumped into a band walking past, on way to an interview.. they knew what was up!

Also got fingered at top of the Statue of Liberty, in NYC- before security tightened up. A massive thrill, as loads of people streaming through the observation window.. finished off properly, on the ferry back!

on a water tube slide- need to be careful, so no kids about.

police cells (public tour)..
