Byron1122, I'm sorry that you had the experience that you did because it is considered a legal crime to expose a child to p 0 r n o g r a p h y. In every State in the U.S., it is considered child abuse to expose a child to p 0 r n - still photos, video, and written p 0 r n o g r a p h i c prose.
Although I've heard many arguments that support p 0 r n as "normal," I am steadfast that it is typically (typically, now) objectifying and doesn't portray what a normal, healthy sexual relationship consists of. The argument generally begins with other cultures that actually have children sleeping in the same living space as their parents who are having sex, and this isn't p 0 r n. Sex is a natural, normal, and healthy aspect of a relationship. What a child is exposed to at that point is what is acceptable/tolerable/expected in a relationship, and most cultures hold to an expectation that the couple will be as discreet as possible. The difference with p 0 r n is that it typically depicts the obejctification (use, abuse, discard) of women in very painful and risky sexual situations that do not generally occur in a typical relationship. Today, girls are unable to view themselves as anything more than objects without any more importance than a disposable lighter.
Now, the reason that p 0 r n is unhealthy for children to view is that, as I typed, it is typically unhealthy visual information about sex, and that children's brains have literally not developed enough for them to process what they are seeing. They do not have the experience and maturity to process the visual information that can (depending upon the material) actually taint their perceptions of what healthy sex is all about.
I would urge you to work on rewiring your thinking to understand that p 0 r n o g r a p h y usually involves paid actors to engage in acts that they would never do with their partners, and they're doing it for a sum of money - much like a nail technician will give someone a manicure or a roofer will place shingles on a roof. p 0 r n does not represent safe, healthy, loving, and respectful sexual interactions.
Best wishes to you.
Byron1122, I am truly sorry for your experiences and a "close friend "might hear your story, but they will not have the training and tools to assist in putting these issues to rest. I strongly and gently urge you to engage in some counseling therapy with a SPECIALIST in child abuse+child sexual abuse.
A counseling therapist will also have the training to remain objective, eupportive, and encouraging without becoming emotionally involved, which are skills that "close friends" may not have developed, yet. To find a competent and strong therapist in your area, call your local domestic violence hotline and talk to the intake person and s|he will provide a list of specialists that can truly help you. Also, Victims' Services may be able to help.
My sincere best wishes to you.
