Sexual Relationships 
Sexual Health 
After an excruciatingly awkward conversation with a girlfriend where we sat back to back and I described in great detail, how to give a blow job, I'm just going to write it all down and help all you ladies out! You're welcome ;)
Just to be clear, I'm not saying you have to do them, because obviously you don't. But you should try it at least once, some girls think it's disgusting, but then they try it and they love it! Especially in a committed relationship where you feel free to explore new things.
Pre blowjob
There are those blowjobs that are quick, very sloppy and spontaneous, obviously you don't need to do anything before. Then there are relaxing, slow burn blowjobs. If you're planning it, and you know you're going to do it, you should definitely take the opportunity to tease him. You should ask your partner to get rid of most/all pubic hair. It can make is harder to perform fellatio. You can try a dirty text, or say something suggestive when you're saying goodbye before you see him next. If you're together you can find someway to tease him, and definitely wear something that makes you feel sexy when you're at home. Could be naked, could be a silk robe.
Just like any other time there should be foreplay. Kiss him, touch him, stroke your hand towards his crotch, but go over his hip instead. Run your hands over his neck, his back, his shoulders, and if he likes it, his hair. Work your way down slowly. You can kiss all the down if you like.
Techniques
Kissing. Kiss his penis and his balls. You can give him light pecks and also extra wet sloppy kisses. Focus kisses on the tip, it's the most sensitive. I think this is a great way to start off.
Licking. Lick the frenulum. It's the very sensitive bit on the underside of the tip. You can rub your tongue over it gently or circle it. (does not work if circumcised) Be very gentle and soft. You can also lick from base to tip, and lick/suck the balls too.
For beginners, or to start off with. You can push the tip to the inside of your cheek, or the roof of the mouth, and use your hands on the rest. This is easier but still pleasurable.
Up and Down. You can start off with simple up and down motions, using your hand to twist the bottom when you come up, or if he's quite large. You can also put you hands on his thigh, or cup/play with his balls.
Sucking. Take in a good 3/4 inches, don't try more for this or you'll gag. You can put your hand at the base and twist gently. Use your mouth to suck and hollow your cheeks. Don't forget to breathe through your nose. This may take time to get good at. Once you can do it, you can touch the frenulum with your tongue at the same time. Also go careful because this can make you lightheaded.
Deep Throating
Don't expect to be a pro at this okay, it's really tough at first, and you don't want to push yourself, because the last thing you want to do is throw up or choke or (eeeek) bite.
It takes practice. When you brush your teeth, slide the brush very slowly to the back of your mouth, as far back as you go without gagging. Then push back slightly further to the point of weak gagging. You should try it with the mouth open and closed, breathing through your nose, concentrate on relaxing your throat. If you do this often, you can desensitize the gag reflex over time, allowing yourself to take in much more of the penis.
Also make sure your man understands how hard it is. When he's in your mouth it's okay to thrust in and out, but in your throat it's extremely uncomfortable, so just make sure he knows to be considerate.
The easiest way to do it, is with you lying on a bed with your head extended over the bed. Here your throat is perfectly aligned and it's much easier, although he will be the one in control of this.
Once you can do it, there's a lot of other cool things you can do, and these are my favourites. When his penis is all the way in you can hum around it, and it produces very powerful sensations. You can also contract your throat on the head of the penis while it's in your throat. Be careful though because this can cause biting if you lose control. And the best in my opinion is deep throating and licking his testicles at the same time. You kind of just hold it there and it's great.
Finishing up
When he's close or actually cumming, the tip is very sensitive, so I normally go gentler for the finale. Licking and gentle sucking. He can absolutely not cum down your throat, it has to be in your mouth. If you does down your throat, I'm telling you, you will gag and there will be teeth. So don't do that. Look him in the eye when he does, and if swallowing repulses you, at least hold it on your fingers and play with it. How would you feel if someone didn't like your taste? It's like a rude awakening, so if you can't swallow, still appreciate. (DON'T SWALLOW IF YOU ARE NOT CERTAIN THAT HE'S CLEAN. In fact if he's not clean = no blowjob)
Additional tips
Try to produce as much saliva as possible, it feels silkier, and it's easier for you to glide you lips and hands.
You must never use teeth. I've heard of girl, putting the flat side of their teeth very gently... and you could try that but when it's actually inside your mouth, you really can't use teeth.
Look him in the eye whenever you can, I feel it makes it more intense.
Behave enthusiastically, instigate, and be a little animalistic for a bit.
You can talk as well, you can say how much you're enjoying it, or you can complement him. You could talk about how turned on you are.
If you trust him, you can put your hands away and he can move your head how he likes. Make sure he's not an oaf though, if he jabs you in the throat, the both of you will end up in ER.
Jump on him and make him surprised. Like after you haven't seen him for awhile or waking up on a lazy Sunday morning.
Anyway, there we go! I can't think of anything else hehe! Have fun everyone! ;) (Gentlemen, would anyone like a lesson in female oral? Happy to provide a similar guide)
