Here's the thing, the reason why most guys suck at making a girl climax is simple, they are just not into it for them. When you have sex, do you enjoy the actual event, or do you strive for what happens afterwards? Same thing with munching. You have to really get into it, have some fun. I stress this for women giving head as well, the best blowjobs i have ever gotten are from enthusiastic women enjoying themselves. think about it this way; do you like the feeling of making your gf happy? If not, then look at it this way-the better you make her feel(ie the more enthusiastic you are, without being totally overzealous) the better the chances are, that ure gonna get something in return.
