Well, just try to relax. When you kiss her, do it with confidence. If you can keep a confident feeling in your head, it should go just fine. Don't take her by surprise. You can touch her face and maybe start by kissing her on the cheek. Always make sure you have soft lips. If you don't, use chapstick daily. Actually a little chapstick when you are kissing can help your lips slide over hers easily. Or, at least wet your lips a little before kissing. It is definitely easier for me to tell you what NOT to do. Don't go right into frenching. Ease into it from a regular kiss. When you go to use your tongue, don't "point" it, keep it flat and don't dart in and out. Does that make sense? Don't be too forceful or use it too fast. Be soft and gentle. Also keep your saliva under control. Make sure you are not giving her any of it! Start by just placing your tongue on hers or running it under her top lip (again, flat). Don't leave it in her mouth too long! Just use it and pull it right back and end with the regular peck kiss. Do a "pulling peck kiss", use your tongue a little and pull it right back with a very slight sucking motion on her lip. Does this make sense? Do everything pretty slowly, not fast. Also, use your hands while kissing her. Don't underestimate the power of that. Touch her face or run them over or in her hair. If the kiss gets more intense, pull her to you. Don't stay stiff, move a little to get into it. You can also kiss her on her neck and under her ear. A trick that usually works to build some excitement, is to kiss her on her neck and cheek then brush across her lips (don't kiss them) to the other side of her face and neck. Keep doing this until you are both dying to kiss on the mouth. This is a great tease. Relax, and good luck!
