My crush told me he wants me to stay innocent for as long as possible after finding out I'm a virgin why?

He knows I want to be in a relationship with him and is very kind and sweet but wants me to stay innocent. I have autism and he doesn't have disabilities at all. He's very understanding and caring about me but he knows I want him to take my virginity and. He said sweetly to please stay innocent for as long as you can. I'm confused... Don't guys usually like virgins?
