You won't get what you want. I'm sorry, but it's NOT going to happen... right now. Maybe later, just not right now. He will get what he wants sexually, but you will end up feeling used because you want more. Or atleast something emotionally that he's not capable of supplying. Take his warning seriously. You will get hurt. I REALLY don't want to be unnecessarily cruel, just honest based on past horrendously painful experiences.
I was in your spot. Its not an easy journey. I wanted more from them and I didnt get it. I got the good friend instead which is nice too. Just becareful and take things slowly. He just may warm up to you
