Strip Away The Lust, The Emotions, And The Infatuation And There is A Lot Of Rational Stuff Going On Here Most People Don’t Realize (and this is the core of what makes the sensual pleasures possible, powerful, and to what degree!)
The First Kiss is VERY Important! Use as many senses as possible
The first time you kiss someone you're very passionately attracted to (with all your senses) it's a shockingly wonderful and all encompassing feeling- like you found the gold at the end of a long beautiful rainbow! But as you develop more respect for them, the feelings you have for them increase and the sensory stimulation also increases. See my other article on: Intoxicating Kisses.
Sometimes different aspects of the person stick out. Their smell, how they look, how their voice sounds when they talk to you softly or sexy in your ear. How they feel when they touch your skin, the softness of their hair, the sound of their breathing, the thumping of their heart, how they squeeze your arms, and sometimes its their taste that turns you on the most. I guarantee you though the more senses you're aware of the more intense you will feel them and remember the experience. The same goes for any memory forged in emotional carrier signals.
The very memory of the last kiss can make the next kiss twice as intense. Before you even kiss them dopamine is released based on the brains reward center's function. When you anticipate something you really want, then get it dopamine is released to force you to remember the successful event so you repeat it. If you don't successfully achieve your goal you feel like crap and that's to punish you so you work harder to achieve it the next time.
This lends some intense variety to kissing someone each time. It's like watching a movie and picking up where the story line left off- enhancing all the moments after it with the information before it!
Each Time You Kiss Your Partner or Make Love To him/her Especially The First Time...
If you know you're going to be kissing someone for the first time, realize this kiss will be a filter through which all following kisses will flow (unless a future kiss is so passionate it will override the first kisses "first impression"), so make it good. Utilize ALL her senses (and yours) in the interaction, especially the first time! (no nothing of an on a super intimate level (rounding the bases?) but in good taste for how long you've known him or her.
Now that we've covered the art and science of passion, let's talk a bit about one of the most powerful "triggers" of emotion where love, intimacy, and memories are concerned- Music. I'll go slightly off topic to explain how music can help you build powerful passion.
