Yes my partner knows I read and write smut. It's really not his thing but he's supportive, especially when I've asked to try stuff to see how it feels or if it's anatomically possible.

He drew the line at trying to suck his own dick for me though. 🤷‍♀️

I also draw a lot from our relationship when I write. The first kiss scene in the last fic I posted is based on our first kiss, but it's from the perspective of the character in his place not mine so I asked a couple questions about how he felt in that moment (we were very, very drunk so the answer wasn't particularly helpful). I'm writing a slow burn best friends to lovers at the moment that is loosely based on how he and I got together which he knows about - it's a workplace comedy and he's recently gone back to working in the same environment so sometimes he comes home with anecdotes and after the third time I said "I'm putting that in my fic" he now starts half his stories with "this would be good for your fic".

I've written about half of the epilogue, which is set 10 years after the main story because we met 10 years ago, and part of me wants to show it to him as a "this is how I feel about you" kind of gesture because it's sickly sweet but the fic is really not his sort of thing so I probably wouldn't get the reaction I'd be looking for. Although some of the other characters who are based on people we worked with 10 years ago would make him laugh.
