Whilst bad breath, a darting tongue and a wet sloppy kiss are rated as the biggest kissing turn-offs according to science, it might also be your smell, taste or even your pheromones that's causing the problem. Being a bad kisser can be a deal breaker, but kissing is more complicated than most people think.
After some serious digging, the answer: yes and no.
While there are things you can do to improve someone's ability and make their kissing a little more your style, there isn't much you can do if they're not willing to change.
You Can Adapt Your Style
Even though everyone has different preferences when it comes to kissing, if you can adapt your technique to what your partner is into, you're likely an excellent kisser. A good kisser knows how to switch up their technique depending on who they're kissing or what stage of arousal they're in.
When they start mauling your mouth, pull away slowly, count for a beat and give them a single, tender, kiss on the lips. It wouldn't hurt to say “I love being kissed really gently” or “I like going slow”. It might feel awkward, but most bad kissers really are crying out for a little instruction.
Continue to be gentle, but be honest and clear. Let her know you're coming from a place of concern and wanting to make a good thing (the relationship aside from kissing/sex) better. Let her know that what is happening is preventing you from enjoying her kisses—and you so want to enjoy her kisses!
Some believe that kissing with tongue is a natural evolutionary progression that aids in mate choice. Others, citing cultures where kissing with tongue is not only absent but looked down upon, believe making out is a specific learned behavior that's gained popularity due to media consumption and globalization.
Not every first kiss, though, is a great kiss. They can be awkward, especially if the moment is not right or even forced. Even still, we are physically wired to tell the difference between a bad kiss from a good kisser and a "this does nothing for me" lipsmack.
If she stiffens or pulls away, that's a sign she's not yet comfortable, and going in for a kiss now probably won't go well. If she blushes, giggles, or smiles, those are signs she's comfortable with you and would possibly be receptive to a kiss.
In John Gottman's relationship research, he was able to find that six seconds is the length of a kiss that can actually create a connection with your partner. In fact, he recommends you have at least one six-second kiss per day.
If it gets to this, just be light-hearted, and focus on the positives, without putting the pressure on them – for example, say you really like how things are going but you don't feel like you have the same kissing style, and ask if you can work together on that.
A bad kisser is almost always inexperienced, and/or doesn't know how to read their partner's body language. They don't understand how to work their mouth/tongue in rhythm with their partner and often get slobbery and click teeth.
People usually consider a kiss sloppy when it leaves saliva on your face, especially outside of your lips. If you or your significant other has to wipe their face or has drool on it, the kiss is probably too sloppy.
As long as you approach it tactfully (avoid comments like, "Ugh! You kiss like my uncle!") and present it in terms of what you prefer rather than what he's doing wrong, he has no reason to get his feelings hurt. If he does, it doesn't bode well for your relationship.
You get all giddy. When you kiss someone, your body releases happy hormones. A rush of dopamine, oxytocin, and serotonin hits your system the moment your lips lock. With this positive cocktail and a heart-fluttering kiss, you'll feel like you're on cloud nine!
Kissing on the jawline is a turn on for many men. You could just move your lips and use a little bit of tongue while doing this. You can also turn on a man by licking his ears. The kiss triangle: So it begins with the lips, you move to the ears, then to the neck and back to the lips.
You can't catch halitosis from another person but you can contract the bad bacteria that cause it from someone else. The bad bacteria can be passed by kissing, sharing utensils, sharing toothbrushes, and can even be transmitted to and from your pets!
