Consider yourself a beginner in the kissing arena and know that beginners aren't supposed to know everything. Without the pressure of having to know, we free ourselves to just try something new and have fun.
Note: Both women and men have said their best partners were not the best-looking, did not have the best bodies, nor were they the ones who knew the most sexual stuff. What they did have was the best attitude about sex
To practice some new kissing techniques, look in a mirror and watch yourself kiss your arm or hand. See and feel what your partner will. Imagine how he will feel your heat, your breath, your moisture and your texture. You may feel silly doing this, but trust me, as with anything else, the more awareness and information you have, the more confidence you will have about doing something. This is the time for you to experiment with nibbling, sucking and licking as elements to add to your kissing repertoire.
Practice using all the areas of your lips. Think about kissing your partner's lips beyond the usual outer edges. Explore these areas and techniques and how they will feel when you next kiss face to face by experimenting in front of the mirror. Test what kissing with your inner lip feels like by kissing your own inner wrist first with a puckered mouth, then with a more softly open mouth, so that you feel the warm, wet inner lip. Use the same lip shape you would if you were going to suck on something.
