We hear the word kinky all the time, for the most part in jokes and allusions, as a method for portraying something explicitly odd. Actually there is no set definition for what "kinky" is.
The difference among an inexperienced and experienced lover is the methods that they use. The first step to make a woman horny is the approach that you will use to cause her to become excited.
Release yourself from any 'magical expectations'. Think of finding where your G spot is as a sexual exploration. If you reach an orgasm, so be it but don't be frustrated if you don't.
The orgasm is the crowning of a successful and highly pleasurable session of sex. It puts a grin on the face of satisfied women and makes men walk with a swagger.
Most women do not really like the very idea of anal intercourse. The most common reason is that they can't imagine why you would want to have such an idea in the first place.
If you tell your partner to spice things up, they might suppose they are a bore to you. So be a little careful and prudent with whatever you want to say and how you say it.
