Lets talk about perspective.  Oral sex is not a chore and shouldn't be viewed as such (unless this is a role play situation of course).  Often, the desire to perform is much more of a turn on important than the skill of the performance itself.  By approaching it with an open mind and enhancing what you love about giving head, it becomes even more fun for everyone involved.  Giving a blow job can be an empowering experience since you are in full control of your partner's pleasure.  Do what feels good to you... if you are trying to do things you don't enjoy then both of you will be able to tell the difference.

So how do you get started?  I like to take my time even getting to the actual blow job.  Start with trailing kisses from his lips, along his jawline, down his neck... keep going down his chest, taking time to lick and nibble his nipples on the way.  While your mouth is working it's way down his body, you can caress his skin with your hands using light strokes.  Kissing down his stomach, stop and linger along his belt line and hip bones.  The whole process is meant to be a slow, sensual journey.  By this time, he will be squirming and anticipating your every move.  When you get to his penis, linger over it with your mouth... without making any physical contact, just allow him to feel the heat of your breath.  Bypassing his goods, kiss and nip your way from his thigh up to his package.  Give the other side some love too!  Now you can get to what he has been waiting for... the actual blow job.  Making eye contact with your lover, begin to stroke his shaft and take him into your mouth.  Eye contact amplifies the already intense sensations for your lover and allows you to relish in his facial expression.  Watching him is a bonus turn on for you too!  You can draw out the initial sensation of your mouth on his penis by swirling your tongue around and kissing down his shaft.  The best blow jobs include not only your mouth, but your hands too!

I could go on and on, but to save you from redundancy, check out this great slideshow for lots more information.  It includes the history of fellatio, spitting vs swallowing, what to eat/drink, anatomy, techniques, and tips & tricks:

Adding an oral sex gel or flavored lube can make things taste yummy and slide more easily as you play.  Sliquid Swirl and Max Head in Sugar Daddy are my personal favorites!
