lol this thing is kind of like kissing your parents except with feeling.
get her on the lips, neck, chest, add some tongue... just experiment with it.
she'll probably like if you be creative and passionate.
don't try the sexual tension thing your first time though, I think it's more important to actually get used to the kissing beforehand.
its just like the approach of women, only I don't think you can be rejected if they're the ones who want you to do it. after the first kiss you'll soon know exactly what you're doing. you don't need to copy anyone, you have the capability to do this with your instincts.
the best advice I can give you is just do it..... kiss her already!!
