It’s National Orgasm Day! NHS Choices excitedly informed us via their Twitter feed.

The tweet, to their 84,600 followers, also included a link to the NHS Choices good sex guide. Who knew everyone’s favourite NHS website had taken an interest in improving the nation’s lovemaking?

“Even the most contented lovers can have fun trying new things”, the guide announces before listing tips on how to “relax into the feel of each other’s’ skin”, the importance of keeping clean (“a certain amount of sweat is fine”) and the “extra thrill” of whispering.

“A sexy phone call leave both of you looking forward to the event for hours or days,” it suggests.

Texts and emails can also be used to build anticipation but, the guide warns, “remember that your employer has the right to access your work email”.

Good point. And as End Game was using a work computer the video entitled “a healthy sex life” had to wait for later.
