Guys often have complaints of having lousy sex with their girlfriends which develops over time.
This frequently leads to infidelity and the guy looking for sex elsewhere or else relying heavy on pornography to fill his needs.
If you are not experiencing awesome sex with your girlfriend, here's something to try: Increase your oral practices.
Now I'm not talking about you receiving oral pleasures, but you giving oral pleasures.
This works amazingly well for the following reason:

• Giving her oral is one of the most pleasurable, pleasing, mind blowing orgasmic things you can do.
  Unfortunately most guys are not good at it and don't do it enough.
  But if you become the master at oral, this is what happens: Your girlfriend transforms.
  She transforms into a hungry, ravenous, loving sex machine who will now want to please you every which way.
  

It works like this: You provide her pleasure (and I mean mind blowing orgasmic pleasure), and then she feels compelled to return the favor.
Matter of fact she will feel extremely guilty if she doesn't return the favor! It's human nature.
You receive a gift or favor from someone, you want to return it.
Sex is no different and applies even more.
Sex lives have been greatly improved by guys who have increased or improved their oral practices, because in return they receive sex acts like they have never experienced, their girlfriends become much more experimental, and the overall need and desire for fantastic sex is present like never before.
But, you have to be GREAT at giving oral.
Learn some proven, mindblowing oral techniques then go to work.
The rewards will be huge.
