Cuddling/cockwarming/comfort-seeking between MCs who don’t talk about it

Hi! As the title says, I’m looking for books where MCs seek comfort in each other and don’t talk about it at first (if they do, then not in depth). MCs who don’t have a prior sexual or romantic relationship.

Maybe it starts platonically or accidentally, maybe they consider themselves “straight” (or not!) - what’s important to me is that they are actively avoiding discussing it, whether for fear that it ends, or they think they shouldn’t be doing this, or any other reason.

Bonus points for some type of “forbidden” relationship or age gap

No’s for this: age play or omegaverse. Thank you!
