Being a prude really doesn't have any connection with what you enjoy just as your sexual experience doesn't really have anything to do with it. Everyone has their own fetishes that generally fall into two categories: the kind they actually want to take part in and the kind that they find the mere idea of it arousing. Expression of your fetishes is important here but it's not really necessarily anything to worry about. Don't feel like you have to force yourself to express it but there's nothing to be ashamed of either. I think writing comics or stories would be a good way to help express what you're feeling. I myself find writing fanfiction a useful endeavor but that's just me. I hope this helped.
