My dad found out I am sexually active at 17 years old? What do I do?

My boyfriend of almost a year are sexually active. He is 18, I am 17. We are both getting ready to graduate, he is going ot UT Austin and I am going to Le Cordon Bleu. We have been dating for a while, and I lost my virginity to him. We always use protection, we have been friends for the longest time, and now my dad found out we are having sex. He isn't talking to me. I don't regret having sex at all. I love my boyfriend, always have. And he loves me. He is very loving. What can I do to get my dad to forgive me? Is it wrong...?
