dw man.. the girl will help you out once you are both naked... you dont have to kiss while actually doing it but if u want to you can try it. althought it might be hard if she is having an orgasm.
you put your thing near her vag, and usually she will help you get it in as you get acquainted to her body... and then you just thrust and such in and out in and out .. harder and deeper with each thrust
.....see how that goes for you .. you can also look online there are a bunch of sites that will help you out (no not porn ) but like just step by steps... . ex: ehow.com
well GOD BLESS YOU, and best of luck my friend. i was worried too my first time and now im totally ok with it
