This way you are always prepared for everything

You're at the bar or club or on a hot date with a hot guy. The evening goes such that you go home with him, but once on the bike, you realize that you have NOTHING with you for the next morning and that you are actually not prepared at all for these kinds of nighttime escapades. You decide to abort the mission and head home, thus missing out on an evening of fun, and that's not fun for anyone. I've said it before, the idea that you can't have sex with someone after the first date is really hopelessly outdated, so ladies, always keep this in your bag and then nothing can go wrong.

Moist wipes

Just a quick fresh touch-up down there and you feel a lot more confident between the sheets. Also ideal for cleaning armpits and face (not with the same wipe, please).

Makeup remover wipes

Of vital importance, for when you come out of the shower at your flame's place the next morning and your mascara is on your knees. Don't assume that this kind of handy stuff is in his man bathroom. Out of sheer desperation, I've used his shaving gel before, but take it from me, that's not exactly a party.

Mini deodorant

Just buy one of those little monsters for a pleasant scent under the armpits the next morning.

Powder

After showering, you've scrubbed the black stuff off your cheeks, and to not completely fall apart, you quickly put on a dab of Les Beiges from Chanel (or other bronzer) for a quick healthy look. 

Clean underwear

A thong doesn't take up much space, and it's just nicer to be able to put on something clean the next morning. This way, you also show that you're a fresh clean person, and that will surely please him.

Charger for your phone

Because not everyone has the same phone, and maybe he has dibs on the charger taken. Nothing worse than not being able to call your girlfriend right away the next morning to tell her what kind of crazy adventure you've ended up in this time.
