What is sex? No one we asked in the last hour really knows, but at least one thing is for sure: the above photo has got it*.

The NYC Taxi Drivers Calendar, which debuted last year, is back with its 2015 edition, which is available now to purchase. The calendar's producers declare: "These drivers put a face to one of the most dedicated workforces in NYC, driving day and night to transport New Yorkers and our guests alike. This year’s calendar features three returning All-Stars and 10 new drivers, and debuts our first ever husband and wife driving duo."

For just $14.99, you can have sex delivered to your home or office or refrigerator every month, in the form of beefcake**. But don't just take our word for it, check out a sneak peek below.

This is the cover of the calendar, which is filled with the poignant hint of sex***.

What is more sex than a man who has lost some of his shirt buttons because he cannot understand how to change a tire?

Okay, puppies are not sex, are they? We're confused again.

This loving cabbie couple is having sex in this photo, according to what we've read about sex on Google****.

This seems a bit off-brand, what with no taxi or taxi-like objects in the photo, but we guess even cabbies need to stop and smell the roses and have sex in public water fountains.

This is interesting, because I have shaved, so have I had sex?

Back on track, food definitely means someone has either just had or is just about to have sex*****. Who needs firemen when they have food sex.

* Whatever IT is. So, can someone please explain to us what IT is?
** And what is beefcake? Is beefcake IT?
*** Help us.
**** Google kind of sounds like it could be a synonym for sex, is it?
***** We think we get it now. If it=what is sex.
