I would say with any new thing, you are having intense feelings because it is brand new and you have not experienced it before. 6 hours is a long time to play for a brand new first time experience. Entirely normal to be smitten with someone who has showed you new and exciting things that are out there.

Maybe you have gotten lucky and found someone you really click with, but need to talk to him about it before you start seeing hearts, flowers and condom packages. He may or may not be interested in an exclusive or sexual relationship. May already be in a relationship or otherwise taken. Talk to him is the best advice i can give but be prepared to not get the answer you are looking for.
