Sudden relationship?

I met this guy we hit it off really well. We had drinks talked vibed one thing led to another we had sex. I have been celibate for one year and supposedly he had been for 7 months. I have had close friends recently pass away less than two months ago. Honestly it felt good to be around him and everything. After our encounter we talked and everyday and seen each other often. We have been on a few dates and have more planned for the upcoming weeks. I'm loving this energy we have. He expressed that he liked me a lot and feel some type of way when I dnt talk to him ( I feel the same way). I guess this is a relationship. He stated that we are exclusive. I just had a history of shutting off when things get too close almost like I reject love. Just needing advice on how to not lose interest or get in my own thoughts and shut off. I really like him.
