How do i give a good blowjob?

Im a never get to go anywhere but when i do get to go out im wild. I've had sex before and gave someone a blowjob, but i dont know if im really doing it right. I wanna make them MOAN when i give them one, how should i do it?

Usually just try something if he dont like it they will tell you somehow. But personally speaking the things that I as a guy like are:
1. how far down your throat you can take it. (deepthroat)
2. wiling to swallow
3. willing to have it come all over your face or breasts
4.your enjoyment don't look like you really are doing a job
5.playing with the balled area
6. suck on the head itself that will drive any guy nuts -short amount of time DON'T stay there he will get bored.
7. A LITTLE bit of teasing. Pull the pants down. Get him all ready then stop. Pull away and sawy back and forth. touch it with the tip of your tongue for second pull back and repaet a couple of times. That thing will be harder before you know i and driving him wild at the same time.
Suggestions:
After he is done cuming suck the rest out of the end. That area is sensitive after ejaculation it will make him go wild.
Take your time some guys love for it to last a long time. Some want it quick and to the point. Most guys Will Tell you what they like and Don't like.
Another thing unless he specifically asks for you to use your teeth don't. It Hurts. Kindof sensitve in that area.
After a Blowjob he may be gearing up to go again( I know I am) maybe give a little peice of that ass that he wants. And he just came so that means he can go all night long before he maybe ready again. (draw you own conclusion)
You know That famous number 69. Well let himsee the pussy while getting the crank dipped and bobbed.
Mix it up a little all guys watch porn-even if they say they don't try some of that stuff.
Start out with alittle Bj the goes vaginal back to bj . Your Guy will love you You just gave him the best of both worlds.

Remember If he enjous it when he is down on you the favor just might be returned.
Have fun Enjoy it yourself. If you do He Will.
Hope that helps

start by making him go down on YOU first, that way he will be hornier for when you repay the favor. If in doubt, ASK him what he likes, is this good? And so on. Practice makes perfect and no technique works the same for different men.
