At some point, you've probably wondered why a guy wouldn't man up and kiss you already. Moments of opportunity would come and pass, but you just couldn't seem to make it to the next level.

The guy should always be the one to make the first move. No question. But if you've ever waited longer than usual for him to move in (past the second date), he's either being a little over-cautious, or hasn't been getting your signals.

Imagine levels of intimacy as gears in a car engine. When you accelerate, you build momentum until you can shift the motor into a higher gear. If you can't gain enough speed, you'll be stuck in first until you do.

The same goes for your intimate development. If you two aren't being physical or playful enough, you're not building the momentum necessary to shift and make the kiss happen. This is a big cause of hesitation for any sexual milestone.

Guys aren't always the best with receiving signals from females. So if you think he's a bit lost, try to find simple physical ways to let him know that "it's on."

One of my favourite ways girls do this is the "sidle-up". The simple act of cuddling yourself into him is a strong signal to his subconscious mind that you like him and want to be touched.

This move isn't restricted to just the couch on movie night. Any time he's sitting or standing is an opportunity. I love it when a girl does it on a walk. And if you're nervous, it's probably the easiest time for you too. There's less focus on the physical contact during a strolling conversation.

The sooner you want a kiss, the earlier you should pull this one out of the bag.

Then there's tongue. Let's not forget the tongue. The responsibility of initiating the usage of tongue lies completely on the girl. It's not required for the first kiss, but you should pop it in there sooner rather than later, just so he can get a feel for how much and when.

Once you've broken the ice, you can happily enter the non-stop make-out phase.

You officially have free license to suck face for no reason, and frequently offend others in public. But I say go ahead, show it off. We can always use a little more love.
