Ok, this essay is more intended for my younger audience, about fourteen and younger. I don't think that the older viewers will get much out of this, except maybe in child-rearing. This overlaps with previous works of mine, but I believe it need be repeated, I also will be including a personal note.
When I was young, my friends and I would fantasize about women, and we'd tell stories to get get our rocks off. Complete works of fiction mind you, dealing with much older women and the stuff of fantasy, like an injection that makes breasts grow and societies where every woman wears a bikini. One such group of stories I had was the C.C.C., also known as the Cindy Crawford Chronicles. I vaguely remember this stuff now, but it was basically she totally wanted whoever was the protagonist, which varied according to who I was telling the story to (the listener was the guy Ms. Crawford desired). In this tale of passion, ski lodges, and ninjas, images of sex and genitalia were brought to bear in most vulgar fashion.
Telling such stories as one comes to grips with one's own sexuality is normal, and I believe quite healthy. It's important you discuss your feelings with your friends in an open manner, and it's important to recieve your friend's feelings in an amicable way. Don't be afraid of who you are, and even if your parents tell you not to look at porn, do so anyway. You need to understand the other gender's anatomy, and I feel that by doing it in ways that involve the imagination and two-dimensional images it prevents kids from playing doctor, which some may consider a worse sin. I understand that age still, for I remember it well, and all I am saying is don't be afraid.
Even if you have feelings that go against societies norms, you should be open with them. Some thoughts may not be considered healthy but some. I'm talking about homosexual feelings. It's okay if that's how you trully feel, and you need to talk to someone you consider safe about these feelings. If it's your parent, fine, if not, a religious figure or school counsler should be next on your list, after that teacher and so forth until you think you know someone that will understand these feelings you have with out rejecting you. It's important to be proud of who you are and what you are thinking. If you're thinking is as such that it harms society, like mass-murder, hopefully you will come to understand why it's bad to have such feelings. But if your feelings are ones that are only about your own happiness, which may involve an alternative lifestyle, it is important for you to explore these feelings to know if it's mearly self doubt, rejection of your parents lifestyle, rejection of an aspect of a person that you find debasing, or if you trullly have these feelings from the bottom of your heart. It may be the key to your happiness, or you may be doing it to spite another.
