Question:Hi! I had sex and I'm only 14. I love having sex (but I've only had sex with one guy). It's such an amazing experience. Does that mean I'm addicted? And even so, I have birth control, but is it possible to get pregnant even if you're on it? I was also wondering if anal sex was a sin. I mean, it's not vaginal, so technically I would still be a virgin. But I'm not, I had real sex. Lots of real sex. I also don't believe in God. I'm guessing that's a sin, too. You probably wouldn't like me too much. But then again, to hate is to sin also. So, you can't really do anything right and have it not be a sin.
Like most people who don't believe in God, you don't understand the Bible. You might be surprised to learn that it is perfectly correct to dislike someone who is proud of their sinful life and have not intentions of changing. "Do I not hate them, O LORD, who hate You? And do I not loathe those who rise up against You? I hate them with perfect hatred; I count them my enemies" (Psalm 139:21-22). You have chosen to be on the losing side -- among the slaves of Satan. Of course I don't like what you have chosen. I hope you will change, but while you remain in your sins, I must battle your false ideas. "For though we walk in the flesh, we do not war according to the flesh. For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ" (II Corinthians 10:3-5).
Addiction means you cannot easily stop because of an uncontrollable craving for what you are addicted to. You could easily stop the fornication (sex outside of marriage), so no you are not addicted. You just find the temporary pleasures of sin alluring. "No temptation has overtaken you except such as is common to man; but God is faithful, who will not allow you to be tempted beyond what you are able, but with the temptation will also make the way of escape, that you may be able to bear it" (I Corinthians 10:13).
In regards to birth control, no contraceptive is 100% effective. Each reduces the odds, but cannot completely eliminate the possibility. See "Contraceptives." More importantly, contraceptives do not eliminate the possibility of transmitting diseases between sexual partners. The odds for catching a sexually transmitted disease is actually quite high, even when a contraceptive is being used. "Whoever commits adultery with a woman lacks understanding; he who does so destroys his own soul. Wounds and dishonor he will get, and his reproach will not be wiped away" (Proverbs 6:32-33).
In regards to anal sex, see "Is anal or oral sex between a married couple a sin?"
I'm really sorry your parents raised such a foolish, childish girl. I hope you will grow up soon, before you damage yourself and others too badly.
