Kissing is an art form. The kissing experience is different for each of us, but the basic fundamentals of kissing remain the same. The first step to kissing is known as finding her comfort level . Make sure she is ready for a kiss and do not start anything until she is comfortable.
Use your hands when kissing. Many people waste their hands while kissing by simply using them as some form of support. You could wrap them around her waist, use them to clutch her back, or massage her scalp. Wherever your hands are, use them. Slowly increase pressure, or gently graze in non-erotic zones like the back, shoulders, arms and face.
Don't only kiss the lips. Kiss her eyes, cheeks, forehead, neck, and hands, and remember her to watch out for her comfort level. She will be more relaxed, and will appreciate your kiss if it's sincere and sexy, and she'll definitely notice if it's fake. Finally, use your imagination.
