How do i kiss my boyfriend just right? help me please!?

we are both new to all this and we're both nervous... we've only cuddled, kissed each others cheeks, and held hands. both of us have never done anything in a relationship, i mean hell, he's never been in a relationship. how do i quickly kiss him just perfectly? eyes open/closed? i mean this would be just a quick kiss. i'd also like to know how to do the long-ish romantic kiss... how to approach it calmly without getting nervous.. i tried to quick kiss him today but i got too scared... i don't think he could be the one to kiss me.... i've thought about like teasing him a bit... like getting close enough to see if he'll do it... but i'd get scared and back away. i think i could do it... but i'd feel like i'm doing it wrong.... i know looking in each others eyes deeply can make it happen, but that's what gets me... i can't look people directly in the eyes... ughhh help!
