Negotiating aftercare and sub drop

New to the submissive side of the spectrum. I’m usually the dominant partner and I am an over communicator when it comes to my subs and their needs. I am finding it a touch hard to do with myself as the submissive. For context it’s a free use dynamic and he has a slight pension for pain. He’s from out of town and we meet in his hotel a few times a year. He’s really everything I’d like to find in a D/s dynamic but his after care is atrocious. How can I go about navigating it so it doesn’t come off as critiquing and not needy. We aren’t romantic or affectionate at all. I think he confuses romance with comfort so he doesn’t ever offer a hug or to lay together until I catch my breath. We finish and he usually will go clean off almost immediately, put his boxer back on, and lay down. It’s almost like “ok I’m going to bed now bye” I’ll quickly rinse off and change and be on my way.

We met this week and it was the roughest we’d played. It was lovely. Truly. We spent hours talking and spending time together out of the hotel beforehand and he always pays. I never lift a finger. After being out for the evening we went back, played consensually, he checked in during, great communication but once he finished No aftercare. I laid their a minute with my legs off the bed composing myself and in the 3 minutes I took to do that he had already grabbed his boxer and laid down, true to fashion i rinsed off and left quickly. I get he’s tired because he’s traveled to a different time zone and is working. I just don’t think he even thinks about it. I knew it wasn’t something he’d really done with the other subs he’s had either. I’m nervous to bring it up because I truly enjoy him and our play is so good but experiencing sub drop a second time and having to navigate alone isn’t my jam. Any ideas on how to offer aftercare without so much affection. We’ve never cuddled or kissed. I’ve sat cozily next to him in bars but that’s about as touchy as we get. So I’m not really sure what I could suggest for next time in terms of what he could do to help it?? How does one minimize it from happening??
