[question] First "love"? Is it common?

I've [26M] never dated before. For 1 month, I'm seeing a guy [23M]. In fact, he was my first "french kiss"We have a lot in common, and our dates have been great. We've already been naked together (in the car, haha), but just playing around.He only had 2 relationships before, 1 only hookups for 1 month, and the other a oficial date for 2 months. He said he wants to marry me! Not in a joking way.I feel happy around him. But sometimes I wonder how would I feel with someone else.Is it "possible" that he is "the one" (for me)? I mean, would I be so luck to find someone special right at first?Maybe I'm overrating him bc he is my "first love"?
