Is it really all about the Sex or all about the Love??

Random...yea I know.
But, lately I've been trying to figure out if all this talk about having or needing a relationship is really all about the sex or is it really all about the love?
I guess it's just that time in teenagers' lives that everyone has to have a significant other or they need to be with someone, but what I'm trying to figure out is what all of this is really all about.
All the time I hear my guy friends talking about "doing" some girl or wanting to "do" some girl and then my girl friends talking about "loving" some guy or wishing some guy would love them...or sometimes the other way around and of course, even girls wanting girls and guys wanting guys. Whatever, the real issue though is: Who is actually being true about it or real about it?
I mean people say that girls think about sex way more than guys, but they just don't say it out loud or aren't so verbal about it as guys are...but is that really what's it about? Or is it that girls just think about love and guys just think about sex?
Personally, I hate all this "sex" talk like it's the thing to do and every one has to do it now or his/her life isn't complete...
Also, I really and truly believe that for the most part it really is about love, even for the guys. There are some people who are just nasty and all they want the physical stuff and that's cool for them, no judgment, but all in all it's all about the love. "It's All About the Love, Dude!" ;o)
I just wish people would be more real about it. There is nothing wrong at all with wanting someone to love or wanting someone to love you; it's a beautiful thing. I see true everyday with people in my family and in my friends.
I'm just saying, it gets really annoying with derogatory phrases and words like, "Ooo I wanna Tap that or Bang that...blah blah" There are obviously worse words out there but it's just so pointless and stupid and then it's like well that's why you don't have anyone because you talk like that.
We are almost adults and you still talk like that? -Good luck, sheesh.
Anyways... my point is: Just Be True to the Love.(period)
