How to give mindblowing oral sex?

How can I give my boyfriend a mind blwoing Bj... He says im good at it... But I want to be fantasticc...
any tips??? Please

Slow teasing, tie his hands to the bedposts and blindfold him Then take your sweet time. When he gets really close, back off and start over again. Do that as many times as you can before he goes mad!

Pinkpearl has the right idea.Try ice and a hot beverage for interesting feelings.Swallowing also never ceases to blow my mind.I know deep feels great,but most of the nerve centers are in the head and just below,especially the underside.Talking dirty is extremely erotic.Most people are too shy or embarresed,but you shouldn`t be embarresed ,I mean look what your doing to him.
Also the term suck really applies,don`t just let it slide in and out,suck it,lick it ,relish it,and love it.

suck it fast and make sure you include the balls, stroke it while you sucking it, keep it wet at all times. tickle under his balls with your tongue, dudes go crazy when females do that...

Here ya go, I found this advice on a medical sexuality site:

Here's How:
Start him off nice and clean.
Social stigma seems to focus on the taste of women’s genitals more than men’s. In fact men can smell and taste just as strong as women. If you're new to fellatio, you might be worried about taste and smell. If so, suggest a sexy bath or shower together and start with a clean slate. You can also add a bit of flavored personal lubricant to his pen*s or put on a flavored condom, which is great for safer oral sex.

Physical comfort is key.
You can’t have fun and perform well if you’re not physically comfortable, and fellatio can put a strain on your neck and jaw. Kneeling before him on a pillow, while he’s standing or sitting, gives you good range of motion and plenty of access. If you’ve had bad experiences with fellatio where you felt lack of control, have him on his back and crouch in between his legs. Giving head can put you in a major power position, if you like that feeling then go for it.

Tease him with touch.
Using your hands first, gently caress his inner thighs, pen*s, testicles, and perineum, paying attention to his reactions (verbal and facial) as you touch certain spots. The most sensitive spot on a guy’s pen*s is the head (known as the glans), especially the frenulum, an indentation between the glans and the shaft on the underside of the pen*s. You might want to brush up on your knowledge of male sexual anatomy , to know what you’re working with.

Give him a lick.
Follow up with your tongue, exploring the same terrain using slow wide strokes with your tongue. Don’t be afraid to use lots of saliva, as this natural lube feels great and helps create friction and suction. There are many STDs that can be passed during fellatio, using flavored condoms is a great way to practice safer sex and deal with any taste you may not like. It is also a perfect way to get guys who say they have difficulty with condoms, to gladly put one on.

Take him in your mouth.
When he’s semi-erect, slowly guide your lips over the tip of his pen*s, making sure your lips cover your teeth as you slide gently down his shaft as far as you’re comfortable. Keep your mouth taut, as the pressure from your lips will feel great as they glide down the pen*s. Putting him in your mouth before he is fully erect is a good way of getting comfortable with the size of his pen*s, particularly if he is in the larger range.

Watch the gag reflex.
If you’re not adept at deep throat (taking the whole pen*s in your mouth), don’t try it or you’ll trigger the gag reflex. It’s not necessary and a similar effect can be achieved with the hand and mouth technique described below. With practice, you can learn to relax your gag reflex and take in more of the pen*s.

Use your mouth and tongue.
As your head travels up the underside of the pen*s, flatten your tongue so it gives his frenulum a nice wide, wet stroke. Don’t be afraid to try different types of licks or kisses—the lips feel good when popped over the ridge of the penis—but perform each stroke repeatedly before changing to give consistent pleasure.

Have fun with the foreskin.
If your partner is uncircumcised, insert your tongue into the foreskin and circle around the head with it. You can also use your fingers to gently massage the head through the foreskin, alternating with deep tongue licks.

Using your mouth and hand, tip #1.
A great blow job incorporates both hands and mouth. Place one hand around the shaft of his pen*s while you move up and down on the top half of his pen*s. Try coordinating your movements so your hand and mouth are going up and down in unison. If you're partner is thrusting, your hand will prevent his pen*s from being pushed too far into your mouth.

Using your mouth and hand, tip #2.
If he likes this combination, bring your hand all the way up the shaft (following your mouth), remove your mouth briefly, use your palm to slide and twist over the head (as if you were juicing an orange), and then glide your hand back down followed by your mouth again. Repeat.

Let him come.
When he’s ready to org**m, keep your movements consistent and firm—don’t slack off. Once he starts ejaculating, see him through with a few strokes and then stop, as most men don’t want continued stimulation once they’ve ejaculated and had an org**m.

To swallow or not to swallow?
This decision is entirely up to you. There's nothing wrong with you if you don't want to, but it's nice to let your partner know it's nothing personal. If you don't want to swallow, and you aren’t familiar with the signs of imminent ejaculation , let him know you want a warning. Remove your mouth as he's about to ejaculate, and continue hand stroking through his org**m.

If you want to know how guys like this to be done...ASK A GUY not one of your girlfriends. (and vice versa if a guy wants to know how best to go down on a girl, ask a girl)

Have fun.

Bible thumpers are idiots and need top be shot.
