(Hint: Leave Your Sleeping Bag and Teddy Bear at Home)
So, it's your first "planned" slumber party at your woman's place. Even if you've already had the drunken pass out after a night out macking, this is a whole new ball game. A pre-planned, sober sleep over means there are high performance expectations.
Since you may not remember the last time you had a dead sober kiss, let alone romp in the sheets, you'd better make some preparations. Here some dos and don'ts for what's appropriate to pack in your sleep over kit. Assume too much and you could end up screwed (or, more importantly, not).

Do Bring a few essentials (toothbrush, razor, deodorant) in a small packpack.
Don't Haul a suitcase full of mousse or meds over. You're not moving in.

Do Pack appropriate sleepwear, like a tshirt and boxers.
Don't Assume you'll be sleeping in the buff. It's presumptuous. And sleeping in footy pajamas or red silk underwear is just scary.

Do Come prepared with protection in a discreet location.
Don't Pull out the K-Y, toys, or jumbo pack of condoms from every pocket of your bag.

Do Bring a nice bottle of wine or some desserts to share.
Don't Bring a case of Corona. Think romance.

Do Repeat her name over and over in your head so you don't shout your ex's on accident.
Don't Snore or drool on her pillow. Or shout the wrong name.

Do Excuse yourself to brush your teeth.
Don't Excuse yourself to leave.
