Introverted

Ok.. so me and my best guy friend decided to give it a try. And when I kiss him.. I feel so much. I feel everything! I'm so glad we tried to do this but one problem.. he is an introvert. He hasn't called himself that but I know that's how he is. He loves to be alone. He likes to go hours playing video games or reading a book. He will turn down a lot of things to do outside of the home just to be alone. I'm not used to that. I'm really extroverted so it's so weird to me that people actually desire to be alone. I try to give him his space and not take it personally but since I'm so extroverted, it bothers me not getting enough attention from him. We only hang every three days or so. We don't text too much because he lays his phone down and gets into a book like he did tonight. I just miss him all of the time it seems like. But I don't want to bring this up too much because he told me from the get go that he needs his time and his space. That's just how he is, and I don't want to interfere with that or be too needy. Anyone else have this issue?
