I've had this sat in my emails since 2009 (ha, post long term relationship confidence wobbles) i have a quick read now and again and seens as this has been resurrected, I feel I should share! Apologies to the original poster, I copied and pasted - probably from handbag over 7 years ago but your words have served me well!!
I am not the author of this...
try to enjoy it. if they know or think you love and worship their cock then they will be incredibly aroused.
secondly remember to take your time, even if he wants to rush (as so many men do) as it will increase the intensity of his orgasm the longer you make him wait for it.
thirdly - eye contact. not always easy but every now and then look up and catch his eye - practise a cheeky smile that you can do more with your eyes and cheeks than mouth (as that will be full). this eye contact suggests sexual confidence and will arouse him and remind him of his fave porn clips (if he's a fan).
then.. there are so many different ways to stimulate a penis other than just **ing it with your mouth as fast as you can.
familiarise yourself with the sensitivity of different areas. of course every man is different but basically the major clusters of nerve endings are in the same places so usually good places to lick sloooowwwwwly are the lemgth of the shaft (veins up the front particularly), the ridge around the base of his helmet, the testicles, either side of the testicles and the perinium and (if he's clean and you're brave) the anus.
in my experience the more teasing the better. work your way down there slowly. if he's an impatient headpusher, tie his hands up so you are completely in control.
kiss and lick slowly but slightly firmly on the tummy, ribs, hips, thighs, inner thigh, then in a little figure of 8 over his testicles gently. then blow gently on him to increase sensitivity.
lick from between the balls to about one inch up the shaft, then down, then up slightly higher, then down...like he was a lolly pop. make a lot of noise, make it nice and wet. say mmmmmm a lot. as you work higher he will anticipate the pleasure of you reaching his helmet where he is most sensitive...so go slowly. make him wait for it...then, when you reach the top encompass the entirety of him (or as much as you can fit) in your wet mouth and fellate him the traditional way for a while as you mmmm and he purrs with pleasure.
now...as disgusting as this sounds..you need to learn to drool. really work up tonnes of spit to make it really wet. you need to coat the whole of him. in doing so you can then use your hand to him at the same time as sucking him so that you are stimulating the whole of him at once. keep a slow steady rhythm. this is called 'gloving'. if you carry on with this alone he will probably cum fairly quickly...but don't let him yet.
make your mouth into a wide, wet O shape and place it over his helmet but don't close your lips tight around him, the O should be bigger than him, now move in circles so the inside of your mouth rubs all around the rim in slow circles.
then use your tongue to make slow circles all the way around the rim of the helmet...go clockwise for a few minutes...then switch to anticlockwise to change the sensation.
when you fellate him traditionally (up down with lips enclosing penis) add a special twist by simulataneously rubbing your tongue up the front of the shaft. you can even wiggle your tongue from side to side or as you do the 'up' strokes and your lips meet the tip you can do one quick swirl of your tongue around his helmet before going down again.
breathe onto him as you fellate him. your in breath will make him feel cooler, your out breath warmer, adding to increased sensation and sensitivity.
enhance this temp change effect if he likes it by having a cool glass of icy water next to the bed and a warm cup of tea (not hot) alternate mouthfuls every now and again and then felate him to give different sensations.
learn to alternate in perfect rhythm...slide your tongue quite firmly up his shaft from balls to tip, then go down on him for just one head bob, then lick then bob then lick then bob. drives (some) men crazy as they can't decide what they like more.
get him as wet as possible. don't be afraid to really dribble over him and do it with the naughty porn star face. then just let yourself go wild and lick him madly all over - his balls, his shaft, the back of the penis (often neglected), just kissing and licking and sucking and mmmmming as wildly as you can so he feels like you are gorging on him and loving every second.
then slow it right down and make him wait a little...kiss sooo tenderly and lick sooo gently, blow on the bits you've licked. let out your sensual side, think like a cat and rub his cock lovingly over your lips (look up and make sure he's watching you), play with it, toy with it, love it, worship it...rub your face all over it - it will be very wet by now but use your whole face to stimulate him by rubbing so gently and lovingly.
then build the pace up again. turn sideways, and purse your lips like you were going to play the flute. moisten them. then making a kissy pout run your lips along the entire length of his cock back and forth so your wet pout is stimulating the front and part of the sides of him. at the same time, his balls (which should now be coated in saliva too) will be easy to simulate with your fingers, gently rubbing in delicate circles or tugging gently in a downward motion to stimulate him and build his orgasm to a crescendo.
above all...variety, rhythm and enthusiasm...plus a lot of saliva are the key things. plus listen to the noises he makes to know what he loves most...but don't give it to him all the time. don't have a set pattern...tease him, make him wait...do what YOU want to do to his cock...so long as he knows his favourites (and his orgasm) are coming he will wait.
an aside note...deep throating. this takes practise...and a lot of love because for most women it's not comfortable. if you can't do it just take him as deep as you can comfortably once in a while to let him feel you just wanna eat him all up. but don't worry as most of the sensitivity is in the tip.
deep throating...this is easiest from a sort of 69 position with woman on top so your head is the other way up to his cock. you have to learn to open and relax the back of your throat and have your head tipped back like a sword swallower. it takes practise to do this without gagging..but the few times i have managed it the rewards have been so massive that it makes me want to keep trying. practise makes perfect.
his orgasm. when you feel him building to orgasm (and you think he deserves it) then keep the rhythm, don't forget to add to the pleasure by gently rubbing his balls, perinium or anus with gentle moistened fingers (you don't poke, just stimulate the outside). pressing gently on the perinium stimulates the male g-spot aka the prostate gland.
some very special men can do a sort of tantric trick with their orgasm (with your help). if they feel their orgasm coming...just before it feels like it's happening they should tell you stop...stop moving, but keep your mouth open...a small amount of semen is usually ejaculated and a mini orgasm takes place but wait a few seconds (10-15 should do it with practise) and then fellate him again...then do the stopping thing again when he tells you he is on the cusp. then start again. you can go on as long as his balls aren't aching but i find 3 orgasms are most men's limits (without a little break anyway)...and the 3rd is the most intense powerful and fantastic and neither of you holds anything back. make sure you make excited encouraging appreciative noises so he knows (or thinks) you are loving it. and when he comes let him come deep in your mouth for some of it, and then open you mouth slightly and hold your tongue just under his helmet as you him to finish his orgasm over your lips and tongue so he can watch it dribbling over you. look up with a cheeky smile, swallow, purr like you've just had a mouthful of chocolate...then move up and kiss him gently and lie together so he can sleep. He will need to. so will you...the next time it had better bloody well be your turn.
