try growing up.
Any couple pretty much ends up having sex only as often as the one who wants it less.
Partly, this is driven by the fact that its not fun to have sex unless BOTH people want to.
And partly this is driven by the fact that the person with less NEED for sex is the one with power over sex in the relationship. They CAN manipulate their partner over the issue of access to sex, and, if both partners happen to be young, naive, and fairly immature, this means that the person who CAN use sex to manipulate their partner almost certainly WILL use sex to manipulate their partner.
She is giving you mixed messages... saying she wants it to happen "naturally" but that is just code for "when she decides to allow it to happen". She is testing you, pressing her advantage... seeing how far she can go before you get angry... seeing if you can remain faithful... seeing what you are willing to do to get next to her.
To be fair, at that age she probably has no real idea what she wants you to do... she is simply exploring the fact that she can drive your conduct and change your actions by grabbing ahold of your vulnerability over sexual desire, like its the reins on her stallion.
Maybe she'll like it if you try the romantic role playing or mystery date games... or maybe she'll decide that's not "natural"... or maybe she'll like it for a month, and then suddenly change her mind, simply to play with your head, keep you guessing, and see what else she can get away with.
Its only to be expected... few human beings are evolved enough, enlightened enough to resist taking advantage of power.
Usually, in your youth, its girls playing this game because they don't have as pressing a need for sex as do young men.
But, for example, it is often men who are willing to provide for a woman, financially... which gives them a power they often abuse.
And almost always, when both people are young, there is a power struggle going on that both are not really self aware of.
The man may try and control things socially ( "they" only go to the places he agrees to go, see the movies he agrees to see, etc..) and the woman tries to balance the equation by controlling what she can control *( you can never do a chore well enough, you never say the right things, she doesn't feel like sex. )
This is all just the ordinary everyday maneuvering of a couple... testing one another... trying to establish who controls what in the relationship.
But, pal... you are being used like a tool. And, if you sit and think hard enough, you will figure out the ways in which you are trying to use her like a tool.
You can, if both are mature and self aware enough, simply sit down and discuss issues of who controls what, openly, and come to cogent agreements on what is or is not fair in terms of trying to control one another... ( which means each having to agree that their partner has control over SOME THINGS )
--but it is almost impossible to get a man to accept that he is trying to control his woman by doing things like insisting on his "guys night out".... and even harder to get a young woman to accept and admit that her capriciousness regarding sex is a form of punishing, rewarding, or simply keeping her boyfriend off-balance as a control game.
Or, if enlightened enough you might try NOT playing games with each other... but that is even rarer.
Or, like most people, you will just keep stumbling thru clumsy, naive attempts by each of you to wrest control over different aspects of each other... and end up slowly building resentments toward each other that tear you apart in 5, 10 or 15 years.
This will happen, even if ONE of you is able to see this for what it is. Because BOTH people have to be equally capable of self knowledge to move beyond it.
Oh... and one other thing... SEX every single day, is just NOT gonna be a reasonable expectation in your life.
It will happen, for while, with any new passion... or, in a long term relationship, you will likely pass thru seasons in which you can't get enough of each other... but there will be dryer spells, too..
Droughts, even.
If you end up averaging two or three times a week, you would be doing better than the vast majority of couples...
And it won't always be because she doesn't want it more often... there will be times when you are too preoccupied to find attention for it, as well.
Deal with it.
