Don't tell him that he sucks at kissing, just tell him how you like it better. Things like "I like small kisses better," work great if he opens his mouth all the way and slobbers.

Remember the Sex and the City episode where Charlotte dated the bad kisser? He used to lick her face all over... it was disgusting. She tried to train him but telling him slowly what she liked (Kiss me softly on the mouth with your lips slightly parted then sloooowly slip your tongue in and caress the tip with mine...) etc, gently training him. Try that... dont tell him straight up that he's a bad kisser but try to retrain him for your styles. Maybe the other girls liked him kissing like that... doubt it, but who knows.

Good luck!

"Don't fall for someone who's not willing to catch you"

Omg I had an ex-boyfriend with the same problem. He was a very sloppy kisser, so I started giving him hints about what i like and taking the lead while kissing....after a couple days, he caught on. Do the same with your ex and see what happens....but yeah, don't tell he's a bad kisster!

gaw, you remind me of this one dude who would flick his tongue in and out of your mouth like a lizard or something *shudder*
just tell him you don't like kissing,lol

I don't agree with justanerd at all! Don't tell him you don't like kissing!

Just guide him with little comments like "soft kisses are so sweet" or "I like this a lot" and show him.

The reason he hasn't improved is probably because no girl has told him the truth. If you like this guy and you're gonna be stuck with him, you'd better coach him.

Protect your heart until you find someone who can do it better than you.

I don't know what to tell you, I don't really like kissing my fiance that much. He is a smoker,(which I hate) and he is not a terrible kisser, but he tends to slobber on me a bit. I have tried to tell him how to change, but I just usually don't do a lot of french kissing with him. I have been really upfront about it, I don't why he doesn't catch on. Also, I wish he would quit smoking!
