Boyfriend of one month likes to joke around about marriage. What does it mean?

Background:

He is turning 27 soon and I'm turning 26 soon. i have been dating this new guy for a little over a month, and he's honestly the sweetest and best looking guy i have ever been with. i don't remember the last time i was this in love. i've been with a decent amount of guys too, so I'm not inexperienced. this relationship just feels super special. In contrast he's only had 2 other girlfriends, but he's dated a lot and just didn't find anyone he really liked.

The relationship moved pretty fast to begin with. we met at a party and had our first date the week after. he wanted me to be his girlfriend less than a week after our first date. and he told me he loved me about a month later. We both agreed that we have never really moved this fast before and have never fallen in love this fast before. and he says that he hasn't been this happy with someone in a long long time.

Things that pertain to my main question:

-After we slept together, we randomly talked about the hilarity of how we met and he joked around about how "its a story to tell the kids one say"

-a month later, we were talking about people's weddings and weird wedding traditions, and he said "i know this is way too soon to even talk about but if we get married, you have to make up weird asian wedding customs and try to make my parents believe them" (im asian, hes white)

-last weekend, he met my family and my brother was talking about his wedding and how him and his wife had to each write/draw a description of their future plans together during marriage for their priest. my boyfriend later told me that he imagined what ours would be like. Since he's a graphic designer and I'm an illustrator, his would be diagrams and planned out and mine would be super illustrated and artsy. and i brought up how awesome our wedding invitations would look.. he said his side would just say WEDDING in cool type with a QR code :)

Questions:

-I've never been with a guy who has brought up marriage like this, but i could actually see myself marrying this guy one day (I KNOW ITS TOO SOON TO KNOW). is it a good thing? is he imagining our future together? or is he just joking around? does it not mean anything? (i'm certain we're not going to get hitched anytime soon. i'm still finishing school and its obviously WAY WAY too soon)

-do you think we're moving too fast? its not like i'm unexperienced and 16.. i have a good number of notches of serious relationships under my belt, and this just feels different.

i'm kind of paranoid also that there might be something wrong with him. what if he's super crazy about me because he's desperate for some reason? or what if this relationship peaks super quick and then he realizes otherwise? he's always constantly complimenting me and randomly stares at me and has a huge smile on his face, and sex is phenomenal for the both of us. its just too good to be true sometimes, and i feel like something has to be wrong with him or go wrong in general. because i never thought guys like this actually existed, at least ones i'm physically super attracted to and get along super well with.

i'm usually super reserved and i try not to move too fast into things(usually in fear of scaring men off), but being with him changed that for some reason.

tl;dr boyfriend of +1month likes to joke around about marriage, does it mean anything significant or is it just joking around?
