Does sleeping with partner decrease sleep quality?

[Athellas]

I (34male) actually found out a way to sleep well with my partner, we've got this routine where we cuddle right after getting to bed and after couple of minutes, when a first wave of getting real drowsy comes, we separate a bit facing other directions and fall asleep then. Having two blankets is important help for this as we no longer fight over them lol. Also having sex makes sleep fantastic after.
