hi. Your not dirty or wrong. But the porn can become a habit and can distort the reality of a sexual relationship which is why its not really recommended for a person under age. . I'm not going to lecture you though because it hard when you have been exposped to sex as a young girl. your boyfriend probably has been curious about porn before. It wont wreck your sex life, you might know more positions than him though. maybe search the net for info thats been written for young people about sex. Go ask alice is a great site to look at.
