I Am Having a Guy-Issue

There is this guy in my life, who has been here for what seems like forever. We are close and can talk about anything... and I mean ANYTHING! We talk shopping, we talk work, we talk kids, we talk sex, we talk erotica. I mean ANYTHING! We have a bond that we share deep inside. He makes my tummy do loops and makes me excited. I love being around him and just the smell of his cologne takes me to the edge of reality. He is soft and gentle. He is caring and passionate. He is patient and kind. What we share is incredible. I am able to share with him, what I don't trust anyone else with... my heart, my soul, my deepest secrets, my strongest desires. And now I have met someone. He is quiet and shy, but strong and supportive. His hugs make me feel secure and his kisses make me melt. I long to feel his kisses as he holds me close. But he doesn't excite me inside like I feel with A. Is this wrong? Am I just confused? Is it possible to have a caring and supportive bond with one person, but feel such a strong physical attraction to another?
