Just to add my opinion in haha.
I feel like I think somewhere along the lines of everyone else. But, for me:
Fucking doesn't need a connection or emotion. You *can* fuck and have a connection, but you don't *need* it (Unless, ya know, you're a Demisexual like myself. XD But that's beside the point). When I'm horny and just needing to get off, and I pin my wife to the bed and use her how I please, that's fucking, to me. It's sort of carnal and more about needs. It's more raw.
Making love is more focused on emotion. Usually I'm wrapped around her as much as possible, we hold hands, lots of kissing, nuzzling. It's *usually* (Not always) slower, more focused on just *feeling* her. Loving her and appreciating everything that is my wife. Being with her. And for me, way more powerful orgasms haha. I still like fucking but the making love orgasms are just... Perfection haha <3 Making love is something you wouldn't do or experience really in a one-night stand for example. The emotions just wouldn't really be there (I'm sure there's exceptions, nothing is ever actually absolute. But, overall at least).
There's also a much different mood and vibe in the room, depending on if we're fucking, having sex (Which I feel like is different from fucking still, but, that's a different discussion
), or making love. It's a little harder to describe but... The atmosphere is different. Even without, well, atmosphere like lighting or sound haha.
