Monogamy is a beautiful thing. There is no wrong way to love and if needing one person to love you and only you unconditionally that's perfect and just how it needs to be for your life.

But there's nothing wrong with being incredibly horny. I'm horny 90% of the time and am always thinking of sex. I find the way people approach me in the bedroom, is the same way they approach me in real life. If I can dominate a man in conversation chances are they will let me dominate them in bed. If my partner is willing to try new thing, communicate to me what they want, or even teach me something they like for me to do. These partners are my favorite and I typically will continue to keep relations with them. If you time to time still think about this other girl, you should probably ask yourself what's lacking in the relationship you're in. What about your relationship is making you think about someone else. I'm sure if you vowed to spend the rest of your life with another person and they did the same. Your wife will probably be willing to do anything for you.
