Our minds rebel against the idea, but some decisions are binary: choosing one excludes the other forevermore. For example, you cannot be both tattooed and non-tattooed; you cannot both be a veteran and know the world of not having faced combat. Experience changes us.
The same is true of innocence. You cannot both be innocent and have experience, although you can try to fake innocence with the usual shallow ploys. For this reason, most intelligent people limit their experience (omigod, so closed-minded) in order to avoid the damage to their psyche done by experience that numbs them to the beauty in life.
