where's the best place you've had sex?

Out in the open on a vast sandy Northumberland beach while nude sunbathing after skinny dipping in the cold sea with my then girlfriend 35 years ago. Simultaneously, feeling the warmth of the sun on my back and the heat of her body underneath me as we fucked on the hot sand was amazing.

It was a glorious experience early on in the most physically passionate relationship of my life. I wish I'd had the opportunity to do it again with my wife.

I don't think it even occurred to us at the time that there might have been people watching from the dunes behind us. Yet I should have known this would have been a possibility because a guy once told me he'd seen couples having sex there oblivious to him hidden amongst the dunes. We probably wouldn't have cared anyway.
