Me and my boyfriend being sexual?

Okay so me and my boyfriend haven't been dating for long but we've dated a few times in the past. Also, we've known each other for a year. He's had sexual relationships before me and I want to have one with him. But I'm a little nervous about giving him head, I just want to do it good because he's gotten head before in the past. So if you can give me any pointers on how to do this it would be great! Also pointers on a hand job is good too. And how can I be more relaxed/open around him while doing it. I really love this kid and I want to do this right.
