Why?
After you and your partner are ready to begin, put on your Glass, say "ok glass, it's time," and when you're through, say "ok glass, pull out."
Obviously, these are the two least sexy sentences ever invented for use in the bedroom, so if you can repeat them with a straight face and remain aroused, you deserve all praise.
If this isn't upsetting enough, you can watch it on your phone.
The website blurb says: "Having sex with Google Glass on brings a completely new perspective. Sex like you've never had it before. Simply swipe to see things from a different angle.
"And enjoy the new view. When you connect your phone, you can even see what it's like from any angle."
Is there an angle? Surely, there are some that should be avoided.
For those concerned about privacy, any recordings are automatically erased after five hours - but someone will eventually devise a way to get around this, as happened recently with Snapchat.
So, if you want to spice up your love life, we recommend minimizing the amount of screens between you and your sweetheart - and just getting out more.
