Advice please

So I've been dating a Christian man for over a year now. he's such a good guy, and I love him so much. at the beginning of our relationship, he made it clear to me that there would be no sexual activity, as that was very important to us. however, we have slipped up several times and have touched each other/had oral. We both know it's wrong and have confessed our sins to God. I know it's possible to find redemption in our relationship, and I do love him, but I'm worried about telling my parents. I'm in college right now, and both myself and my boyfriend are very close to my parents. I feel like if I tell them, they will feel as though he betrayed their trust (even though the fault rests on both of us) and suggest that we end our relationship or not give him their blessing if we ever want to get married. What should I do?
