well heres my 2 cents

when making out, try kissing her neck. girls love it. I love when my girlfriend kisses my neck as well. The move up to her ear, blow in it, nibble on it, lick it, and whisper sumthing in her ear like "your fuckin sexy" or "or i want you"

if that goes well kiss her down her stomach till you get to her hips. kiss her and lick her all down there. thats what usually works for me so hopefully you get lucky

good luck bro

later
