If you don't mind shounen ai there's a bunch but no sex ever. So let me know if you want titles for that.
http://www.mangago.zone/read-manga/merry_checker/ this one has the sleeping thing.
Oh and Super Lovers has this, but there's also a pretty big age gap...so ya know keep that in mind...
I don't remember the sleeping thing specifically but if you want some that have a nice buildup with like an "aw they love each other feel" before they get together here's some
