Bedrooms are for sex or sleeping. If you can't sleep after sex is over, it's okay to sleep apart.
1. Your partner has a cold, the flu or anything otherwise catching
2. Your partner snores
3. Your partner steals the covers
4. Your sleeping partner whacks you, strangles you, hogs the bed, or rolls you in the mattress like a hot dog
5. Your partner’s feet (or something else) stink it up under the covers
