Search Results: should i ask for my first kiss

there's this cute guy that I've recently been seeing
But im 23 and he's 21
I've never dated any guy thats younger than me coz most of them are inexperienced and immature
All my exes were older
But this guy seems mature and has a well paid job and knows what he wants in life
Our first date: he took me to dinner and movie
Second date: he booked dinner for us at an expensive restaurant in the city and dessert after
Third date: we went for dinner (cheaper this time since I suggested the restaurant) and he took me to my favorite cake shop and he bought me a whole box of cakes (they were expensive cakes!)
He kissed me after the second date
But he's never tried to touch me sexually
I did feel a connection between us and im quite physically attracted to him
He asked if I wanted to be serious with him coz he wants this to go somewhere
He ask me if my parents would like him or if i care about his background
He tells me im cute and gorgeous all the time
Should i pursue this?
Or guys his age are not actually mature enough?

So there's this cute guy I met
The first date he took me to dinner at nice restaurant, movie and then a long drive
The second date he took me to this expensive restaurant in the city and then dessert
he's always wanting to see me often these past 2 weeks but I was too busy
But im 23 and he's 21 so im abit hesitant
I have never dated anyone younger than me and I think guys that are younger than me are mostly immature and inexperienced
But from the way this guy handles himself, he's got a good job already and he's quite mature
After the 2nd date, he dropped me home and kissed me
We made out for 10 mins
And then after that, he messaged me:
Him - thanks for tonight cutie, hope you had fun, you're the cutest girl I've met😘
Me - aw hope you did too 😊
Him - did you want something serious?
Me - yeah i do if there's a connection
Him - what about us?
Me - i think we should spend more time together, dont u reckon?
Him - yeh i agree. But to be honest, im not gonna sit here and hide it, i really like you. you're nice and easygoing, you seem loyal, and you know where you want in life like I do.
Me - aw thanks yea i like u too , ur a nice guy and im surprised you're actually quite mature for your age
Him - thanks. So let me know if u free this Sunday
Me - yeh ok i will
Him - by the way, you're gorgeous
Me - aw thanks
Is he asking to be in a serious relationship with me?
Is this too fast?
Bad sign?

He used to message first all the time.. Then we met up, kissed, I paid for his food we had lunch etc. Went home got into an argument because he thinks I don't like him anymore and that's why I don't message him first. I start showing him a lot of love/attention.
He asks for nudes - I send thirst traps not real nudes. He doesn't text first anymore - takes ages to reply - any time I say something cute like "I like you" or "I want you" he replies with "uh huh" or a heart or smiley face
WHAT CAN I DO TO GET HIS ATTENTION AGAIN N MAKE HIM LIKE ME
I really like him :(
