I don't think sex is ever special or important until its with someone who matters to you.
Not to pick on you for saying this, but that is one of my biggest pet peeves about people; having the attitude that sex doesn't matter "UNTIL" something.
Sex doesn't matter until it's with someone you love.
Sex doesn't matter until you're married.
Sex doesn't matter until you're good at it.
Etc.
To me, sex ALWAYS matters. There are people who say that it's "just sex", as if it's no big deal, but it's usually those same people who claim that sex is "just sex" UNTIL something...which is contradictory to their portrayed mentality on the issue. If they truly believe that it's "just sex", then it should ALWAYS be "just sex" and nothing more. Yet, for those people, it's not. You can't have it both ways.
Another thing that bugs me is when people use relationships or love as the deciding factor as to whether or not sex is something special. First of all, it should always be something special, no matter who you're with. Secondly (and this is obviously my personal feeling on the matter), you shouldn't be having sex with someone you don't love in the first place, especially if you're not in a relationship with them already. So, to use that as a deciding factor on the importance of the sex you're having is just a stupid thing to do in my opinion.
Also, if a girl has sex with 100 guys before I meet her, that's going to mean something to me. It may not mean anything to her, but the sex you have doesn't only effect you and you alone. For instance, if you are in a relationship and your partner cheats on you, would you not be upset? Of course you would. Why? Because, sex is always important. Whether you are in a relationship or not, whether you are in love or not, whether you are the person having it or not, sex is aaaaalways important and will aaaaalways mean something.
These are obviously not societal facts. In fact, I'm willing to bet that most of our society doesn't agree with me. These are just my feelings on the issue. And, like I said, I'm not picking on you personally.
