Couples manage to become a subset of their species, with their own communication signals and everything. Although it might take quite some time for two people to be completely used to each other, once they do, they develop some real fascinating quirks of their own.

There are quite a few things that no individual would ever think of doing/sharing with another person; that is until they’ve been long enough that there are no more boundaries.

Here are some things couples do after being together a long time:

Bathroom

Using the bathroom simultaneously for their different morning routines is perhaps the first sign of real intimacy amongst a couple. And it does save a hell lot of time.

Pimples

A pimple and blackheads popping is something that you might not even ask your best friend to do for you. Well, it is gross, but apparently not gross enough to hold long-time partners back.

Smell

Anytime one of them is in doubt about their body odor, they have no qualms about raising their armpits to their better half. For a smell test you know, perfectly natural.

Burping

Burping in front of others without covering your mouth or a shy, little apology later is perhaps the best form of shamelessness and intimacy that humans are capable of.

Period

Period talks are a taboo, sometimes even amongst the best of the friends’ group. But once you’ve been with someone long enough, it no longer surprises either of you how casually terms like cramps, texture, and flow are brought up.

Farting

Another bodily function that we all are very secretive about is farting. Funny how, something which could have perhaps ended everything on the first date, now works to strengthen the relationship.

Morning Breath

Everyone who has a bad case of morning breath knows the struggle of waking up before your partner to go brush your teeth so they are none the wiser. But no long-term couple has to worry
about these little things.

Toothbrush

Using each other’s toothbrush is something that exclusively long-term couples do. Somehow, no rational human would ever do it willingly. But spend enough time with the love of your life and
it seems like the most natural thing to do.

Teeth

Stopping your partner mid-sentence just to get out that piece of spinach stuck in their teeth, is the most natural thing you do in a relationship. Who needs floss, right?

Being casual

When a couple starts dating, both the partners spend copious amounts of time and products to keep their respective body hair in check. All that is forgotten once you spend enough time with someone.

Puke

Also, when you live long enough with someone, helping them puke their guts out isn’t just that gross anymore.

Nicknames

And somehow, the amount of time a couple has spent together is equally proportional to how outlandish or ridiculous they have a nickname for each other get.
