Very nice post... this things are so important. I'd also like to spotlight the importance of affection. Doesn't matter if you are sleeping with the love of your life or a random girl you've just met, you have to do it with affection. Affection is something every woman likes. I'm not trying to say you should be too romantic and boring all the time while in bed. But you have to find the balance between treating girls as if they were whores and at the same time your little angel, and love of your life.
For instance, my gf loves when we're in missionary position and I grab her nape gently and firmly with my right hand while I move my left hand very affectionately all over her face and ocasionaly kissing her mouth slowly ...at the same time I'm screwing her very hard below and saying dirty things next to her ears. It just drives her CRAZY. Multiple orgasms guaranteed.
