My public sex experiences are limited to say the least...
However...

I used to work in HMV on Oxford Street, the one opposite Bond St. tube station. Owing to a particularly geeky taste in music for a 23 year old, I found myself working in the Jazz / World / Queasy Listening / Soundtracks / Other Crap We Couldn't Fit Anywhere Else bit on the first floor.

It was not well lit up there, kind of like a bunker filled with CDs, dust, and old people. In particular there was a very dark corner at the back of the room, just near 'Italy' in world music, fact fans.

One fine day, the guy who ran the world music section came running over to me excitedly... there was a couple enjoying oral delights in the corner! RIGHT NOW!!!

Going over to see if this was really true (well you've got to look haven't you), my legendary customer service got the better of me and I politely enquired to the bobbing head and prostrate form in front of me:

"Errr... can I help you with anything?"
