I have thought long and hard about this question, what is sex. I wasn't sure and really still am not sure quite how to answer it because for me I am still not sure I can define it. Sex to me isn't a clear cut, black and white thing.
From the time I started having sex and up until three years ago sex for me was exactly as Susie definition explained it. A penis in a vagina. That was sex as I knew it. I didn't like it, didn't really want it, but did it because one, I wanted kids, and two because I felt it was something I had to do, my "wifely" duty so to speak. I absolutely hated it.
Three years ago that all changed for me. Sex became something I wanted, something I needed, something I craved.
My mother always told me that sex between two people in love was the most beautiful thing in the world besides the site of your new born baby for the first time. I never understood that until that fateful day three years ago.
I think the answer to this question is one that changes all the time, even within a constant relationship, one with the same two players, it changes.
For example, when that relationship first started, while I wanted to please him, I was more interested in making sure for the first time in 15 years I was getting pleased. Make no mistake, his needs were taken care of and I loved doing it.
But as our relationship grew, so did our love for each other, and so did the answer to the question of what is sex.
Until I met him, missionary was really all I knew. It was boring, plain and very uneventful. Once in a while we might toss in the occasional doggy style, but not usually.
I remember the first time we had sex in missionary position. It was something to behold. I can't explain to you why it was so different. I didn't cum. Physically speaking while it was a whole lot different than my previous relationship, it was still missionary position. Mentally though, because of my feelings for him, it was very different. It was slow, methodical, sweet. We had a mental connection that was so strong, one that I had never felt before. It was beautiful and magical, so much so that it made me cry after wards. I am not a crier, ever!
Sex drastically changed after that for me. It no longer was about me, what I wanted, needed, or what felt good. It became all about him, his needs, desires and wants. If I was pleased in the process, well then that was a bonus. Sex became all about him.
Oddly enough I believe he was having the same thoughts, and at the same time. He was only concerned with pleasing me, giving me what I wanted and needed. It almost became a game with us as to who could please the other more.
And while sometimes we would, for lack of better terms, "fuck", and other times we would, make love, the fact that we were in love brought everything to a much higher level that no one can understand unless you are truly, madly, and deeply in love with the person you are with. We may be going at each other like lions in heat, that higher love is still there making it no longer just the act of sex, but the deepness of mental sex.
I know a lot of this probably doesn't make any sense at all. Putting a definition on what sex is to me is very hard made more difficult with deep emotions thrown into the mix.
All I can say is that today, as I sit here, sex for me is the most beautiful thing, only defined by the players involved, and only truly appreciated by two people in love with each other.
