Maybe you could give us all a lesson. While you are at it, let your gf know what an oral sex god you are. I'm sure she will learn to enjoy your special techniques.
I showed her my certification, I showed her the list of satisfied women, and I let her read the one complaint I got when I was 14.
The best lesson I could ever give you is to start w/ some good foreplay, get her excited before you ever attempt to give a woman oral. Once in position, try the A motion, work to the B and then the C. If one of these 3 letter motions gets her fired up stick w/ her favorite letter. If no pleasure is achieved move on to the letter D, E, AND F, continue thru the alphet til you get to Z, if the Z doesn't do it you may @ the wrong hole, check to make sure her breasts are facing up and then start w/ the small case letters, sometimes it's just a small adjustment to get her excited. If the letters don't work try numbers, skip 1,2, and 6, they are too much like letters you've already done. Don't let it seem you're new as you go thru the alphet, mix it up a little, kiss her inner thigh or move back up to her breasts, keep the attention flowing and avoid talking, this will only confuse her or break her concentration, if that happens you might have to start over, If she's a blond you might find urself taking her to dinner again. Once you've established a comfortable stanz and you're confident she's getting more and more aroused don't over do it, move inside w/ the tonge a little, never give her the whole thing @ once, you want her to WANT it, make her desire you, always keep a little back till she ready to explode and then never give her more than she can handle, you want this to last, you want to be a good lover and unless it's a quickie the longer the better. When she can't hold back any longer (her hands pushing ur head down hard is a good sign) stop, kiss her body all the way up to her mouth, if she wants to kiss you she will, if she turns her head kiss her kneck and her ears, spend a little time teasing her, wisper in her ear, give out a small snort and go right for her breasts. Make eye contact, let her know you're happy to be with her and you're not thinking about the football game. She's turned on, her engine is warm/hot, she'll stay like this for a while so you don't have to rush around, take ur time, ask her what she'd like next and then do it. If @ this time she wants to be kissed, and you have good penis control, slip it in but just a little, don't be too eager, allow her to control the sex part, just let her know you also are ready to go.
A little more than just the oral part but it all just flows as part of the night.
Oh, most of this I was LMAO.
