According to the Huffington Post, one such gift are sex checks. The description boasts, "Who says money can't buy you love?" which we're pretty sure was the original slogan for prostitution. 

Another is a gym membership. Everyone wants a gym membership, but no one wants to be told they need one. 

Never give porn to your other half. While one generally wants Valentine's Day to culminate in sexual congress, the gift of porn most likely strikes the wrong tone. 

'Sleepwalk With Me' is a great movie, and we could not love it more. But Mike Birbiglia's directorial debut is so painfully honest about a relationship that isn't meant to be, it's inspired several break-ups. Save this one for any other holiday. 

The Tandem Glove - this just screams codependence. You don't want your partner re-evaluating your relationship with his/her therapist on Valentine's Day. 

This Valentine's Day, only one gift says "I have terrible taste and I'm even worse in bed," and that is the 'Fifty Shades Of Grey' toy collection. 

A snake can be an amazing pet for the right person, but as a Valentine's gift it probably sends the wrong message. 

The complete 'Saw' collection on blu-ray, massage chair, a bible, name tattoo are such other gifts that could ruin your Valentine's Day. 

Also, don't turn up with nothing. Everyone likes to say they don't care about Valentine's Day, but the bottom line is that no one wants to feel forgotten or unappreciated by the person they're with.
