Guys, What should I do to make our relationship work again?

My boyfriend can't accept my past, I mean the sexual part. He said he needed more time, but he can't get it out of his head now. Some of my friends told me to dump him for his immature response, but I like him a lot. I don't even know how to text him or act like there's nothing happened.
