Hey MariaS. Don't worry about buying a book if you want to bring your partner to climax with a BJ the best thing to do is talk to him about what he likes and dosn't like. Try different methods like using your hand aswell as mouth or more or less tounge. even trying different positions can make all the difference. Listen to the way he reacts to things you do if you don't get any reaction from somthing move on to somthing else. I have never and i mean NEVER! met a guy that dosn't like getting his dick sucked. remember the old saying practice makes perfect. Cheers
