I had an experience with a guy years ago who wouldn't kiss, or fuck. I found him so attractive that I thought no big deal. Wrong. While the sex was really good, the intimacy of the sex act was missing for me. From then on, I swore I would only sleep with someone who liked kissing as much as I do. Imagine my surprise, when years later, I run in to the guy and decide to give it another try, and he's sticking his tongue down my throat. My reasoning of why? I think when I first met him he was truly bisexual, and was lacking in experience with guys. Prob had more experience with women. Years later, and a lot of experimenting with guys, he was more confident, sexually with guys. Now, he can do both. He can be inside a guy, and kiss him at the same time. What a bonus......
