the way it has played into my life, casual sex was always fun, but never something really needed, it was more for the thrill, and little else...
When it came to a solid relationship it played a very important role in expressing feelings and thoughts and all that in ways that other forms of communications can't express.
now I know this is alittle harder for the virgin/or non-love based active members, but here I'll go and try to put it into words..
When there is a relationship that is based on true, and real love, not a school age crush, or some such, but a truthful love...Sex has a very different feel to it. time slips away, the world slips away ( granted it does anyway if your a multiple " big O'er like myself) but it creates a moment in time which feels like forever, though it may be only for a moment...the mind is quiet, but the senses are worked up to the point where ever muscle movement, every breath, every subtle reaction of your mate is noticed, their scent ( by now very pheromone heavy)intoxicates the senses.. your mind is free, your body races like it did when you first met the person...even long after the " honeymoon has ended" Married for nearly a decade now, and two kids, and it is those moments I feel like a school girl again.... you share a moment in all forms, and it's very difficult to describe really and do it justice, but there is always a feeling of trust, and a peace that just is not there with a casual encounter, and re-affirms the feeling of being needed, and cherished...
not as well put as I would have liked, but thats my spin anyway.
