If he thinks your innocent and you know you are you shouldn't be so quick to change that, if he says your innocent and he's making no effort to change that it may just mean that the innocence he sees in you he has no desire in taking away right now. He might be taking it slow. And thats ok. Don't rush into the physical aspects of being in a relationship. Just take it slow and have fun also don't push him into doing the things you want. If you do you may lose him.
