I can't claim to speak for every woman when I tell you how I love to be kissed. At the very least the following kissing tips will give you some great techniques to try on your partner and an insight into one woman's mind. :)
Be Careful With that Tongue
French kissing can be a marvelous experience, but don't dive in with your tongue too soon. Personally, I am turned off somewhat when a man puts his tongue in my mouth during a first kiss (ie: the kiss goodnight after a first date). Another example of using your tongue too soon is when you maneuver it into her mouth seconds after your lips touch. Save the rush for the an appropriate, passionate moment
Use Those Hands
The last guy I was involved with worked wonders with his hands. I'm not talking about sexual groping either. This guy would run his fingers through my hair, up and down my back, over my arms, while kissing me. Try caressing the small of her back (the area just above her butt that curves in) and her face, trace her ears with the tips of your fingers, intertwine your hands with hers, etc. Antonio Banderas once told men to look at the lingerie a woman wears, it lightly touches her body, just barely caresses her curves, he said that is the way a man should touch a woman.
Cup her Face in Your Hands
This is VERY romantic! While kissing her, slide your hand along her lower jaw and cradle it in your palm.
Open your Eyes
Personally, I love making eye contact once and awhile during a kiss. It's not for everyone though. Unless your lady tells you she likes it, don't initiate eye contact in the middle of a deep or passionate kiss, it breaks concentration and is NOT romantic.
A great way to have some romantic eye contact during kissing is to slow down to the point of almost stopping the kiss. Start giving her short little kisses on and around her mouth. Open your eyes to look at her while doing this, give her a little smile. Then close your eyes again and slowly work your way into a deeper, sensual kiss.
Kiss Her Forehead
Wow, this is simple but great. I remember the first time a guy kissed my forehead. It was a goodnight kiss and the only kiss he gave me that night. It was short and sweet and very memorable. I was in awe of it for days after the fact! Move in slowly to plant the kiss and let your lips linger on her skin for a second or two.
Do This with Your Tongue...
The following is a guaranteed way to cause my head drop back and a soft moan to escape my lips. Try it on your partner.
While kissing, curve your tongue upwards and under her upper lip. It should end up between her gums and her lip. Flicker it around or swipe it across the inside of her lip. This might tickle, but it feels divine.
Try Cold Water, Wine or Candy
The most fun I've had kissing involved some exchange of food or liquid between my mouth and my partner's. Take a drink of cold water and pull your lady tight to your mouth by placing your hand on the back of her head. Open your mouth and let the water flow into her mouth. Try this with wine, candy or any delicious liquid.
Take the Above one Step Further
I remember sitting on my bedroom floor eating cake and pudding sauce with my ex. The sauce was delicious and when his was gone, I discretely placed some of mine on the tip of my tongue and French kissed him. He loved it, I loved it, and so we finished off the rest of my sauce in that fashion. Very sensual.
Don't Suck too Hard!
A gentle suck on the lower lip is nice, but when you start leaving black and blue marks, you've gone too far. Seriously, I've been left with black and blue marks in the past...not good. Start off slowly and gauge her reaction, some people really love having their lips and tongue tightly sucked on.
Lavish her With Kisses
If she has long hair, try this move:
Lift her hair off her neck with one hand. Then lean down and give her little kisses all over her neck and collar bone, go behind her neck and ears too. When you are done, let her hair fall, take her face in both hands and lay the deepest, most romantic kiss on her lips you can possibly conjure up. Now that's heaven...
