Scorpio guy unable to talk about feelings

Hi guys.
So I’ve been dating this ♏️ Sun and Mercury (conjunction, Mercury is under the beams, 6.7 degrees away from the Sun) guy with Pisces Moon and Mars (Virgo rising but I don’t think this matters here) for 4 months now. We have major age difference, I’m 39 and he’s 22.
It started as sex only (immediate attraction, the synastry is really good) and then we fell in love, at least that’s how I feel. It never was said out loud. I’m an Aquarius Sun and Mercury with Aries Moon and Mars. Both of us have Sagittarius Venus, but his is in the beginning of the sign and mine is in the end.
So the issue I have is that he really REALLY doesn’t talk much about feelings. Or…at all? We met online and our online conversations are mostly something like, him: “Hi X : ) How are you? What are you up to today? Want to meet?” “Hi, all well, yes! Meet at 8 pm?” “Yes, deal”. - and that’s it. It’s a first time for me a guy never texts a date follow up, never sexts and never even compliments me in an online OR offline conversation.
HOWEVER when we are together he is really, REALLY physically affectionate. It’s not just the amazing sex, but he kisses me like thousands of times during a date, holds my face in his hands, stares deeply and lovingly in my eyes, caresses my face, strokes my hair. And with this all, after which I FEEL he loves me, there’s never ever a single word spoken about it. Or about how he feels about me and us at all.
I can only suppose he’s an “actions speak louder than words” guy (and so far his actions spoke well) but…damn, there needs to be some sort of verbal communication, right? Like we’ve had a first uncomfortable situation recently where my feelings were a bit hurt (99.9% sure it was unintentional on his side) and I’d have benefited from us talking about that and what really happened but he was just silent and upset and then again “healed” me with thousands of kisses.
His Mercury sextiles his Virgo Jupiter and trines Cancer Saturn. No “bad” aspects.
How do I act on that? I know applying silly pressure like “why are you silent” etc doesn’t work, but what do I do?..
