Watched the How I Met Your Mother episode Naked Man recently and I discovered that they actually do have the full list of 50 reasons to have sex (and not just the few they show in the episode). They are as follows:
Because you can’t get to sleep.
Your friend told you about a new position.
Paratrooping/Bangin’ for roof.
Nothing good on TV.
Because you’re in a hotel.
It’s half time.
Celebrate recent weight loss.
You finally get the chance to show your childhood bed some action.
You’re already at their place and don’t want to have to move your car.
Show off new lingerie.
Celebrate major victory by favorite team and/or political candidate.
Your chance to do it in a specific location (ex: airplane, Burger King bathroom).
To prove we’re not in a rut.
Just shaved legs.
Forgot to buy a birthday present.
"Lets Get It On" by Marvin Gaye is playing on the radio.
Celebrating the joy of life after a near-death experience.
Your one chance with a celebrity.
Time an egg.
To avoid cleaning, studying or work of any kind.
She wants to.
It’s cold outside.
Cheer someone up (pity).
Keeping up with the neighbors.
Your roommate is out of town and you can do it on the couch.
Some very protected sex to celebrate the fact that I’m not/we’re not/you’re not pregnant.
They have air-conditioning and you don’t.
Because he/she is from one of the countries you haven’t had sex with a person from yet.
"Damn, your calves look good in those cargo shorts" sex.
Called/texted the wrong person but she was into it anyway.
Because she looked like your superhot cousin and this is the closest it’ll ever get to being okay.
Breaking in a new apartment.
Because he said he loves you and you’re not ready to say it back yet.
Wingman diving on the friend grenade.
Your condoms are about to expire.
It’s getting a little hard.
Miscommunication (cheetos sex).
To reinforce good behavior (such as shaving + good dental hygiene).
