I know a lot of girls struggle with this and they're not sure if they are good enough - well, here is a little guide for you girls so you can make your man a more satisfied guy that is smiling all day:)
Giving great oral sex is an art - an art you need to practice if you want to get really good at it. Step number one is having a good attitude. What's a good attitude for oral sex - well, you need to be completely into it - and I mean REALLY into it. If you enjoy giving it, he'll enjoy receiving it. This may sound as if it was simple, but too many of you girls out there believe that technique is more important than attitude. It is not. Without a proper attitude the whole thing just won't be "it", it will be just another average BJ.
So now that you know what's a good "blow job attitude" - the next question is - How to convey it? There are a few ways - first of all, maintain eye contact naturally. The more you look up at him the better. This way you will not only create a connection - but you'll also see his reactions and get feedback from him. You have to feel him on a deeper level and learn to read his reactions.
The next thing you can do for conveying a good attitude is making sounds - moan a lot, talk dirty to him and even tell him you enjoy/love doing it. As I've said, the more you enjoy giving him oral, the more he will love receiving it.
Step number four is - smiling. Nothing will convey a good attitude than a nice smile - so once you get a bit tired, smile, then keep on going, or giggle in a naughty way.
This is all just basic stuff - there is a lot of psychology behind giving a guy great oral, some girls know it, some don't - the best part of it all is that it is learn-able, and you MUST learn How to Give Your Boyfriend The Best Oral to keep him and make him want you more than any other girl.
