Do you go au natural around your partner, chat to them while naked and do their laundry? You've officially hit the comfort zone.
New research reveals that relationships hit the comfort phase after exactly 11 months and 24 days - when you're happy to squeeze each other's spots, leave the toilet door open and tell all about ex-partners.
The research analysed 2,000 couples and found it takes almost a year to get used to sharing your life and living space with a significant other.
And the key signs you've entered the comfort zone include allowing your other half to see you when ill, without make-up on and in your lounging clothes.
Using the toilet without locking the door, feeling free to cry in front of your partner and letting them look after you when poorly are other sure signs of being in a comfortable.
