Hate to tell you this, but your boyfriend doesn't love you. He doesn't care about you. He wants to get in your pants and thats all. A few times of that and he'll get bored and move on to his next conquest.
Save yourself for marriage. Trust me. Nothing but pain and regret comes from sex before marriage. It also is good to help weed out the men in your life who are only after bedding you vs a man who genuinely cares about you.
And yes, the bible does not believe in sex outside of marriage. Sex outside of marriage is so bad, its even one of the only reasons God permits divorce.
Sex before marriage puts you at risk of STD's, pregnancy before marriage, being used by men, forming stronger emotional bonds with short term relationships making breakups harder on you. Not to mention going against God's will.
If i were you i'd skip dating for the next few years, learn what you believe about sex, God, grow in your walk, learn about marriage and mature a bit. Because you do not sound ready to be in a relationship at this point. Not to be mean, just being honest. There's so much more you could do with your life at your age than worry about dating and sex. Utilize your age and time to enhance your life and improve yourself instead.
