How do i give my boyfriend a blowjob?

how do I suck my boyfriend Penis??? because when I get married I have 2 get him a blow job

There's no proper or best way to do fellatio. There's only two people, each unique, wanting to share some interest. And each has their own wants and needs to satisfy. These can't be fit into the correct say, a certain pattern good for all, at all times. You must find your own way, what's good and comfortable for you.

Here's a couple of websites that provide tips for giving a blowjob (fellatio)

ifyou know how to suck a lolipop then you will know how 2 suck a penis just use your tounge a lot and make sure you dont bite

Rule 1: No teeth unless he says he likes that. Some guys love it, some guys REALLY don't. Best to ask first.

Rule 2: Lots of saliva. The more spit, the better for you both. Feels good for him and it's easier for you to have smooth
motions and it won't pinch or pull any skin.

I like to start with lots of rubbing on the outside of his clothes and make sure he's good and hard. Undo his pants,
but don't remove them completely yet. Stroke him slowly and make out for a little bit, kiss his chin and neck, lick, suck
and nibble his earlobes, work your way down to his nipples. Start gently, not a lot of guys like it rough if they have
sensitive nipples, obviously. Ask him if he likes all of these things and store it all in your memory bank for next time.
Get him to lie back and kiss down his chest down to his pants. If he already has them off, that's good too. If they're on,
pull them down yourself, gently and slowly. A good blowjob has a little bit of teasing in it as well. He wants it, yes,
but it's much better if he NEEDS it.

Ask him beforehand to tell you when he likes something or doesn't like something.
Generally you can start with kissing and licking up and down the shaft, swirl/flick your tongue around the head
(the most sensitive part). Make sure he's good and lubed up, lol!
Open your mouth a bit, tuck your lips over your teeth and take him in your mouth, little bit at first,
then more when you're comfortable. In my personal experience, it's good to start slowly at first and get a rhythym going.
Speed up and slow down. Listen to his noises and if you can see his toes, watch for them to curl or spread out--
this is a very good thing. If he's in your mouth, though, keep sucking.

Your jaw can get sore after a while your first few times, so switch it up once in a while.
Use your hand to stroke the shaft while you're licking and kissing the head,
basically keep the motion going either with your hand or your mouth.

Use your free hand to GENTLY play with his balls, kiss them or lick them. They aren't just for decoration.
Don't be intimidated by them! They like some attention too.

Another good thing I found is to get a good grip on his shaft and take him in your mouth, touching your lips to your hand.
Keep them touching and bob up and down on him, synchronizing them, while sucking on him, like of like a suction-y,
wet, tunnel...this drive my boyfriend crazy, in a good way, of course.

Swallowing is completely up to you. Some girls like it, some girls don't.
Guys have intense orgasms if you keep on sucking while they're coming.
The taste can be kind of salty, but it's different between guys.
Have a glass of juice or something beside the bed so if you don't like the taste, you can wash it down quickly.
Most guys will warn you when they're about to come, so make your decision beforehand, or during...
if you're enjoying what you're doing then you may want to experience the result.
Just don't decide too late and then panic when he tells you.

Hope it helps, and by all means, have fun! Ask him to reciprocate later if you're turned on as well.
It's a two-way street!
