Valentine's Day is the day of romance, so keep this in mind guys: A study on kissing found that women based their decision of whether they would sleep with a man ... on his kissing abilities!

So make sure you don't kiss like this ...

• The Lizard: Your tongue darts in and out of her mouth like a reptile probing for its next victim.
   
• The Roto Rooter: Your tongue ventures so far down her throat that it actually begins to choke her.
   
• The Swordfish: You operate your tongue much like a swordfish, and use your nose in a blunt and violent manner.
   
• The Deep Sea Diver: You rarely come up for air.
   
• Frozen in Time:You never change the position, posture, or angle of your head.
   
• The Squid: You seem to emit an awful smell and taste. All she can think of is how to slip you a breath mint. (Askmen.com)

Just Asking ... What is the worst kind of kisser? Have you ever ended a relationship with someone because of the way they kissed?
