Okay the very first rule of kissing is to not think about it so much ! It will just come naturally. If you try to get everything perfect and you over think it , the kiss will feel really awkward ! But here's just the basic steps and tips! :D
Step 1 - Make Sure You're Kissable!
I can not stress this step enough. Before you go on your date, you have to make sure that no matter what , you have good hygiene. Brush your teeth really well, use some chap stick if needed, and bring mints! No one wants to kiss a nasty mouth !
Step 2 - Lean In For The Kiss!
You'll be able to tell when the time is right so don't be nervous. Okay here's what you need to do as the guy. Look into her eyes , play with her hair (just push a strand away from her face or something), and place one hand on the side of her face or neck. I know it sounds weird , but you've seen movies. you know what I'm talking about. Relax your lips, and keep looking into her eyes until right before your lips touch.
Step 3 - Just Kiss Already!
At this point, your lips are touching.(omg fangirling) Be sure not to press too hard, but don't be too gentle, either. Now this part should come naturally as I was saying before, so just go with the flow . You'll know what to do. I'm assuming you mean making out kissing by the way, which a lot of people get nervous about. You're basically just kissing over and over again without taking breaks in between haha :3
Well I hope this helped ! Good Luck ! <3
