Great passion


So I’m in a new sexual relationship. Been dating this guy a little over 3 months and we have great sex. He understands the importance of foreplay and he gives the best oral I’ve ever had. But there is no passion. No spark. I really like him but that chemical reaction is not there. He indulges my fantasies and my desires. He I open and willing to try new thing but I’m still lacking the passion. Do I just need to be patient or could it never develop?
