15 Things You Should Know Before Dating Your Best Friend

1. You'll be alarmed at how attractive you suddenly find him

His sex appeal, which you previously thought of as…well, non-existent, is suddenly unavoidably obvious. Like a great big, sexy elephant in the room. Is it me or is it hot in here? *fans self*

2. You'll get jealous of your mutual female friends

She might be your closest girl mate, but as soon as she starts talking to him in that classically flirty cute way she does, you'll want to hit her. In the face. With a wet fish.

3. There will be no 'chase'

You won't be stalking his every Facebook movement or accidentally bumping into him on a night out – because you already know his daily routines. And his entire relationship history. And his whole life story. No small talk needed here, thanks.

4. It's a risky business

Because you could end up with no BF or BFF. And that, my friends, is a lose-lose situation. So he'd better make it worth the risk.

5. You might break his heart

And there's not much more that's worse than upsetting the life long best friend you care about massively. Except maybe drinking a cold cup of tea. That's pretty bad too.

6. Seeing his penis for the first time is utterly terrifying

What if it's not as big as you want and you can't pretend it's not disappointing? You weren't even consciously aware he had one up til now, never mind the pressure of unwrapping it with the same expectation as a bloody Christmas present. Why isn't there a manual for these things?

7. You'll regret having told him anything, ever

Because, sadly, he will remember you telling him about that time you practically died from choking on your ex's penis while giving him an over-enthusiastic blow job. Awks.

8. You won't mind crying in front of him

He already knows how you get when you're premenstrual. While you definitely wouldn't be weeping over Olaf nearly melting in Frozen this early on in any other relationship, you totally don't care with him. I mean, he's seen you cry over this part at least four times before.

9. It'll be awkward with his mum

Before, you were the one she bitched to about the wild hussies making banshee noises from her son's bedroom at the weekend. Now you're the wild hussy. Get ready for some awkward scantily-clad bathroom run-ins.

10. It'll be awkward with his dad

Of course it's going to be awkward. He's known you since you were young enough to wet the bed (sober) and now his son is shagging you.

11. There are no secrets

He already knows about all the guys you've slept with. And he doesn't mind the fact that sometimes you still wear a head brace at night. Or that you've re-read all the Harry Potter books at least eight times. In fact, these are probably some of the reasons he fell in love with you in the first place.

12. You'll need to ditch all previous crushes

Continuing to declare your undying love for The Gos is not going to win you any points with this new boyfriend. Even though he knows about all the posters in your room.

13. You'll believe it's all destiny

And then want to slap yourself across the face for being such a sap. Destiny? Yeah right. But then you remember that your horoscope did suggest you'd find lifelong happiness this month, so you allow yourself to descend into another daydream about the marriage and kids you'll definitely have together one day.

14. You'll start making an effort

And he'll observe that there's "something different" about you. Although you'd like to believe it's just because views you in a whole new, radiant light all of a sudden, in reality you know it's only because you've got a bit of mascara on and stopped picking your nose in front of him.

15. You'll still argue about the same old shit

It doesn't matter that you're a couple now. His obsessive love for country music will still piss you off. His corny jokes will be more embarrassing than before. His shower singing will continue to make you want to scream. But it's ok, because those things are also kind of the reason you love him. Forget meeting guys during happy hour – you've found your happily ever after right under your nose. Hopefully. *crosses fingers and has minor panic attack*
