First time is always weird don't worry
Just remember to keep it wet, don't go all slow and sensual, go fast up and down his whole length (or as much of it as you can)
The head is the most sensitive part (basically like a guys clit) swirl your tongue around it, press your tongue into it gently, wiggle your tongue back and forth as you go up and down, hold whatever you can't get in your mouth in your hand to steady it. Curl your lips over your teeth so you don't knick him.
The more you do it the more natural it will become. And ask if you don't know what to do, any guy would be glad to tell you what he wants and likes! dont worry about deepthroating (a lot of girls can't do it) and tell him to tell you when he's going to finish. It's ok if he doesn't, you can just use bjs as foreplay to get him wet before having sex (if you're having sex)
To get him to cum it has to be continuous and fast up and down bobbing. If you don't want it in your mouth just tell him before hand and have towels or tissues ready
