A lot of people ask how to kiss, here's what I've found works. Feel free to add so that I can steal your ideas for later.

Practice! If you're really ballsy ask your crush or local girl-next-door to help you.

I know you want more of an answer so here we go:

Hygiene

Brush and floss everyday. If you want to use mouthwash use half and half peroxide and water for 30 seconds. Bad breath (and oral tastes) come from bacteria multiplying in your mouth when you eat sugars. When those sugars run out bacteria metabolize proteins from dead cells in your mouth and release noxious gases. Peroxide debrides your mouth and kills those germs; effectively fixing both roots of the bad breath issue.

If you're uncertain what your breath is like then lick the back of your hand, let it dry, and smell the spot. You shouldn't smell anything.

NOTE: peroxide is caustic to your tissues and teeth. Don't use too often, too long, AND DO NOT SWALLOW. Following up with a fluoride rinse will help your teeth maintain enamel integrity.

Smooth lips count here so keep up with your facial hygiene and lip protection.

The process of:

When you feel like the moment is right you need to go for it. I won't school you on the build up because you didn't ask. One of the best ways to start is to gently, with your fingertips, turn her head towards yours by her chin and kiss. If you happen to be behind her, maybe spooning on the couch, very lightly start on the back of her neck. Behind or on her ears works well. Start gently!

The Mechanics

Kissing doesn't take a lot of talent. Usually when a girl let's you kiss her she is sufficiently attracted to you that you just have to not do anything idiotic like biting her eyelid.

Part your lips slightly, 1cm or less, and softly plant. The point is to have changing tactile stimulation. The lips are only matched by the fingertips and sex organs for nerve endings and are very sensitive. Know how it's kind of sexy for a girl to suck on something like a lollipop or your fingers because you automatically associate the act with fellatio? What do you think girls associate with their lips? I digress.

Rhythmically close and open your mouth, matching each others' tempo and varying forcefulness. Pay attention to her cues and be sure to keep your mouth moist with saliva but not sloppy. Press your lips against her so that the areas just inside the exposed parts of your lips are seeing action.

The Zones

Obviously you want to kiss her mouth. Other hot places are directly on, behind, and beneath the ear, the collar bone area, all over the neck, the tops of her breasts, and the stomach. Focus on brushing these areas softly with your lips with your kissing motion and get creative with your licking. Don't leave too much saliva. Blowing very,very softly on these areas can be a game breaker at the right stage. Escalate slowly but constantly, confidently, and firmly.

If she tries something you haven't seen before then try back on her. Try different approaches with licking and sucking on her to switch it up and escalate.

If you use all this you had better have a condom because she will be DTF with a quickness and she will be PISSED if you aren't prepared. Make out and fuck like a tiger.

Edit: I completely forgot about biting and it's my favorite thing. Not too hard but a sharp bite at the right time is awesome. Get a feel for how rough your girl likes it and go to town.
